The Importance of Welding in Industry

Welding plays a significant role in various industries on which the world depends, for example, aviation, automotive and construction industries, among others. More than 70% of fabricated works come directly from welding. Direct examples where vessel welding plays a role are, in road works, gates, fences, kitchen devices and ware, pipelines, vehicles, planes, space shuttles, and artillery, among others.

While these welding provisions may seem insignificant, the welding industry largely contributes to a country’s economy. The manufacturing industry, in which welding plays a huge role, accounts for 12% of GDP in the USA and employs over 12 million people (data from the American Welding Society).

With increased population growth comes an increased demand for commercial products and infrastructure produced directly or indirectly by the welding industry. It means the industry will contribute even more to the country’s GDP.

 

Understanding the Welding Process

Welding involves fusing two or more metals, plastic or wood (the original material to be used during welding services is referred to as filler or consumable). It forms a weldment (the resulting joint) from the parent material (the cojoined parts). The different types of welds include the slot weld, plug weld, full penetration weld, and partial penetration weld (partial joint penetration).

 

Welding methods

1. Gas Metal Arc Welding (GMAW/MIG)

It’s commonly found in construction and automotive settings. Here, a thin wire acts as an electrode to create an electric arc. It heats up as a welder feeds it through a welding instrument while using a shielding gas (carbon dioxide, argon, oxygen or helium) to keep the area free of airborne contaminants and works on stainless steel, copper, and nickel, among others.

 

2. Shielded Metal Arc Welding (SMAW/Stick Welding)

SMAW is a low-cost process that’s not so strong on the quality side. It’s popular among home-shop welders and uses a flux-coated electrode consumable in a manual two-handed process. It has similarities to the TIG method but melts the stick rod and flux coat to emit the gas that shields the welded section from contaminants.

 

3. Gas Tungsten Arc Welding (GTAW/TIG)

It’s most common for thin and non-ferrous metals. It’s an advanced welding form centred around patience, experience and skill. Its major difference from other methods is its use of a non-consumable tungsten electrode when forming the weld.

 

4. Flux Cored Arc Welding (FCAW)

FCAW is a distinct two-process welding method where the welder feeds wire continuously during the progression. In one part, shielding gas takes centre stage while in the other, self-shielding agents that are an offshoot of decomposed flux material within the wire enable the process. The latter enables outdoor welding and is typically used in construction due to its high speed and portability.

 

Others include; Submerged Arc Welding, Thermit Welding, Gas Welding, Forge Welding, Electron Beam Welding, Resistance Welding, Plasma Arc Welding, and Atomic Hydrogen Welding.

 

The importance of adhering to quality and safety standards in welding.

Adopting safety standards in producing quality welded material ensures the well-being of workers and end product consumers. Having strong welds that will not unexpectedly break, causing injuries is fundamental.

Quality means the aesthetics, which are crucial to consumers, are catered for as well since poorly welded products are easily noticeable. It also all but guarantees the performance, longevity and durability of a product, since the joints will withstand stress and tension easily.

Quality metal works also reflect well on the company that produces the work. Attention to detail, concern for customer wellbeing, regard for quality, taking pride in work done and great customer service are all essential in attracting and retaining customers.

 

Innovations in Welding Technology:

There is a rise in more efficient welding techniques that increase the speed with which tasks are completed. Robotic welding systems take the lead where the control offered by computers is leveraged to weld metals with enhanced precision and speed. It’s effective and facilitates welder wellbeing. Robotics, the cost-effective approach, will soon lead to the automation of the whole welding industry, eventually eliminating the human error element. It’s possible since the parts follow specific instructions from computer programs.

Laser welding tech is one of the latest advancements in the welding world. The laser beams rapidly melt the metal, fusing the target area as required. The high-precision method enables fine work with the most intricate of parts. It’s estimated to be up to 10 times faster than MIG welding. Since the heat used is moderate, it’s a popular form in medical and automotive work.

Large-format metal additive manufacturing and Robotic metal 3D printing are interchangeable terms that refer to Wire arc additive manufacturing. It is another breakthrough method that fuses automated MIG (metal inert gas) or laser welding with 3D printing. This modern approach has enabled the industrial sector to produce huge metal parts in reduced lead times while eliminating costly supply-chain challenges.

Quick Turn Around Machining: A Guide for the Post-Pandemic Era

Posted on by ER Machining

No one planned for it, but it came nevertheless. The world as we know it would never be the same after it took a big hit from the Covid-19 virus. So widespread was the impact that every industry has a tale to tell.

Losses were epic, and the laws of supply and demand were pushed to the limit to overcome the trying times. Maintenance schedules didn’t matter, as staying safe became the immediate goal.

However, as there is a gradual opening of economic activities, it becomes expedient for industries to gain stability. While several factors could get them back on their feet, quick turnaround machining would play an immense role.

This article will look into how quick turnaround machining can help to steady industries after the pandemic.

What is quick turnaround machining?

Quick turnaround machining refers to the services of machine shops with the capacity to reduce lead times. More so, it involves preparing and responding to the emergency needs of clients.

Houston machine shops provide this service to a wide range of industries. Knowing that needs show up at an unplanned time, they have several machinery and professionals who interpret problems and provide apt solutions.

Besides, these companies usually stock up materials that are commonly used. The practice further reduces lead times. Companies in need of custom-made and non-standard parts can get what they need in times as little as a day. Other services they offer include maintenance,

Phases of Industrial Stability

According to studies, there are three expedient phases industries must navigate before attaining industrial stability. These include technical, psychological, and economic phases. Quick turnaround services can help to achieve these needs, as we would see in a moment.

A. Technical phases

Machines have been highly efficient in tackling production issues. Lags due to human variables are in many ways minimized using CNC machining service. Since the bulk of the work lies on program writing and execution by a computer, these variables are absentia.

The advanced technology of CNC machining services bypasses the often tedious processes that manual engineering pose to regaining balance. Not only does this technology get the production wheel rolling, it makes it do so fast.

B. Psychological phases

The concept of psychological balance covers both clients and manufacturers. Quick turnaround machining would doubtlessly reduce conflict between both parties. Nothing else would boost confidence after a prolonged period of inactivity than covering much ground in little time.

As a result, both sides would sooner share the can-do spirit, vital to propelling the industry.

C. Economic phases

Finance is a crucial industrial aspect. Minimizing losses and maximizing profits should be the priority of companies looking to rise from previous setbacks. Also, they must increase in capacity to handle several customers at a time.

Without a doubt, companies offering CNC machining services are playing their part in ensuring a fast turnaround for multiple works. The swift turnaround eventually keeps industries at work. That means they can dare to do more than ever before to cover lost grounds.

 

Why do industries need stability as a matter of urgency?

Industrial stability is the key to a functioning economy. No nation in the world can thrive without industries. Some of these challenges are a result of

1. There is an increased need for maintenance

Perhaps you are just about to open up your manufacturing firm after a long period of hibernation. While it is good news, there is the fear that some machines may have picked up a fault due to unuse and absence of maintenance. Getting those parts back to work or replacing them on time should be your concern. Finding a spare may prove difficult due to the use of custom parts or general unavailability. For that, there is a need for machine shops with fast machining services.

2. Industries are racing against time

As industries are trying to jump-start their activities, there is the need to make up for lost grounds. The backlogs are there, and so are the new demands. As a result, you would have a longer operation time than before.

The scenario would not be overwhelming to employees alone but the machines as well. There’ll be a need to keep engines in optimum condition at all times. For this, quick turnaround machining is indispensable, and there are Houston machine shops on the ready.

Meanwhile, the fallow period of activities has also been a chance for several industries to go back to the drawing board. As a result, there are continuous hurdles to scale.

 

3. There is a need to reduce cost

The period of inactivity brought about much loss to companies. Managing available funds for production would be a cogent issue in times such time as we are.

The longer the production time, the more the financial implication. The rapid time for producing machine parts helps reduce expenses. Again, products must get to the market at the right time for optimum sales. Industries know this too well and so work to reduce production time.

To do this, they need fast machining services to meet the increased need for pieces of machinery. Machine shops in Houston have the expertise and equipment to serve various industries all in good time.

Bottom Line

There is no need to reiterate the importance of industries to the economic development of any nation. Getting them up and working is not a matter of deliberation but that of urgency. Houston machine shops are taking the lead to make this happen by providing quick turnaround machining with a view to steadying industrial growth in these post-pandemic times.
