3 Traits Every Successful Welder Has

The most outstanding professional welders have three key characteristics that make them exceptional. Welding proficiency shows in the results of a welder’s work, which is based on drawing from a solid skill set, properly applying expertise, and having a particular flair for the work. A successful welder understands the craft, continues to learn, and finds a specific niche.

Tips for Eye Safety While Welding

As someone who has worn glasses since the 4th grade one of my greatest fears has always been that I would go blind.  So this last week of National Safety Month I wanted to write about Eye Protection.

Fortunately, welding helmets are a lot more comfortable than what’s shown in this Library of Congress photo from 1944!

Protect your Eyes While Welding

It sounds obvious, but eye injuries are one of the most common types of injuries on the welding job.  And in the case of arc flash–which you can get even if you turn your head away instead of wearing UV protection–the damage can accumulate over time.  And even seemingly innocuous tasks can result in foreign material in your eye, so always use eye  protection: goggles, safety glasses, or welding helmets.

Safety Glasses for Welding

At Arc-Zone we developed this Guide to Eye Care for Welders (.pdf), print it out and keep it in your shop.  There’s a section on what to do in an emergency that I hope you never use, but keep it in an easily accessible spot if you ever find yourself in an emergency….

Weld Like A Pro™ TIP: Interference

Another great TIG Torch tip from Weldcraft®

Prevent high frequency interference by keeping torch and work cables as short as possible and closely bundled.

Remember to ground your power source according to the installation instructions provided in the operator’s manual.rightquote

 

 

TIG Torch Cables

TIG Torch cables: rubber vs. vinyl

And while we’re talking cables, if you’re in the market for a top quality TIG torch, consider upgrading to the Weldcraft Premium TIG Torch packages that include flexible rubber cable / hose leads.  Note that Arc-Zone also sells the CK Worldwide torch packages with the SuperFlex cable set.  Here’s what Arc-Zone’s Joe Welder (aka CEO and founder Jim Watson) has to say:

We generally recommend the rubber hose leads as opposed to vinyl. They are more flexible and easier to handle. Vinyl plastic hoses are more economical, but they get stiff over time and the water hose / power cable are susceptible to damage from heat generated by the power cable, along with the water pressure from the water-cooling system — you have a recipe for hose failure.  Not to mention that the hoses melt quickly when they come in contact with a hot TIG rod, or welded part!

You can read the full article, “Rubber Verses Vinyl Plastic Hoses Which is Better?” over on the JoeWelder.com blog–>

And finally, did you know you can get cables custom-made-to-order for your TIG Torch at Arc-Zone?  Whatever length you need, give the Arc-Zone Customer Care team a call and our technicians will put a quote together for you.  Keep in mind there is a 5-7 day lead time involved– but you’ll end up with top quality cables that work for you welding application.

Where in the World is High Purity Welding?

An Overview of High Purity Welding

For October, we’re celebrating high purity welding here on CarmenElectrode.com, starting with this overview. High purity welding procedures are utilized in a variety of industries where the metal being welded requires a super clean environment in order to achieve optimal weld results.

In other words, any industry where it is important to have the best weld you can possibly achieve.

In the aerospace industry, as you may well imagine, obtaining a super strong weld joint is imperative to the safety success of an aircraft. A while back, The Fabricator magazine featured an article on Orbital welding for the space program, where every weld must pass the “highest of purity and integrity tests.” These welds must hold up deep in space!

Nuclear piping is another industry where you don’t want any weld to fail. Titanium, a notably reactive metal, is a good choice for the nuclear power industry due its resistance to seawater corrosion—not to mention the strength of titanium, when welded correctly of course. Arc-Zone’s own Jim Watson (aka Joe Welder) prepared a good overview of titanium welding a while back.

 

 

Another industry that comes to mind for high purity welding is food processing (including dairy and breweries) where stainless steel pipe systems carry food product from one place in a factory to another. In food processing, the welds must all be smooth and free of any occlusions, or any little nooks and crannies where bacteria could grow. To achieve that kind of weld, the inside of the pipe—the backside of the weld—must be protected from oxygen as much as the front side. And you can’t stop with just a good weld—finishing is important too. Check out these tips, also from The Fabricator magazine, “Finishing stainless steel for food-grade applications.”

In piping systems where good clean water needs to be delivered, such as the pharmaceutical industry, the pipes must also be free of contamination, and not prone to rust. The semiconductor industry also requires high purity welding to ensure smooth welds (inside and out) and prevent contamination of the system. This video demonstrates the inspection of the inside of the weld…

Reactive metals, like stainless steel, titanium, and inconel also require attention not only to the weld process and specialized accessories, but to the weld environment as well. Some applications may require a Clean Shop with a dedicated area for storage of materials and a dedicated work area where air drafts and contamination can be minimized, or a purge chamber. For a run-down on accessories for creating high purity welds, check out the article on JoeWelder.com, “Overview of accessories for high purity welding.”
