How to Weld Aluminum Safely

How to Weld Aluminum Safely

Welding is one of the most hazardous professions out there. Even one mistake can cost you a life. Of course, this is in the worst-case scenario.

However, even if everything goes well, doing welding daily involves many hidden dangers that can be the cause of various diseases, disorders, and problems with health. 

That’s why it’s always better to know all these important aspects before you get down to work. Welding aluminum is especially dangerous and has its own peculiarities.

This is the reason we’ve put this guide on how to weld aluminum safely. Hopefully, it will help you minimize the risks.

Welding Dangers: Welding Fumes and Gases

As welding is a complex and hazardous occupation, every welder daily complies with certain safety standards. It concerns their equipment, clothing, and, of course, the rules of occupational health and safety.

Nevertheless, some risks are still common and may harm welders regardless of their will and uniform. In particular, it involves risks from welding fumes and gases. Let’s figure them out.

Plastic Laser Welding

Plastic Laser Welding (1)

Most people are familiar with the concept of welding as a procedure to join two metallic pieces. The image that people have of the said procedure is of an electric arc producing intense light and spatter.

However, welding is not exclusive to metals. Welding can be used to join two or more plastic pieces together. Not just any plastic, though.

And not the traditional welding methods used for joining metallic pieces are used for welding of plastic. Let’s elaborate.

In different industries, joining plastic pieces permanently is sometimes necessary. Examples abound, including some toys, car parts, outdoor furniture, and more. The welding process involves the fusing of the plastic material.

Welding is done with thermoplastics only. This type of plastic has the property of melting with heat. This property facilitates the welding process.

The principle is simple. The plastic pieces are heated until they melt. These parts must be of compatible thermoplastic materials.

Then, a filler material is added as in some metal welding techniques such as MIG and stick welding. In some cases, however, no filler material is needed.

Welding is a risky work that predetermines much caution. Welders who are daily involved in Stick, MIG, TIG, plasma cutting, and grinding, among others, may be easily exposed to UV/IR radiation and toxic fumes.

The danger especially comes from manganese fumes, as they may harm the breathing system, then the brain, and lead to many severe diseases, including Parkinson’s. Let’s briefly cover this phenomenon and figure out how to prevent manganese poisoning.

8 Tips for Aluminum Gas Welding Using the Gas Tungsten Arc Process

8 Tips for Aluminium Gas Welding

Welding is a process widely used for industrial applications. Professional welders have plenty of work in the construction and manufacturing industries. DIY enthusiasts often weld for repairs and other home projects.

However, unlike DIY enthusiasts, professional welders master several welding methods. Commonly, different welding methods are grouped into four categories:

  • Gas Metal Arc Welding or GMAW, in which the welder uses a wire as the electrode;
  • Gas Tungsten Arc Welding or GTAW, in which the welder uses a tungsten electrode;
  • Shielded Metal Arc Welding or SMAW, in which the welder uses a consumable metal stick as the electrode. This is by far the most popular welding method and the preferred by DIY hobbyists;
  • Flux Cored Arc Welding or FCAW, in which a wire with a flux core is used as the electrode.

Of the above welding methods, GTAW is the most common for non-ferrous metals. This is also one of the most difficult welding methods to learn and master. Common metals, for which this welding technique is quite effective, include aluminum and copper.

This is the reason why some industries in which these materials are used demand GTAW professionals constantly. One of these industries is aerospace manufacturing.

History of Welding Helmets

The History of Welding Helmets

Knowing the basics of welding applications also predetermines the knowledge of the history of its equipment. Each professional involved in arc welding or even salesmen should know what welding helmets, in particular, stand for, their upgrade steps since introduction to the market, alongside their numerous pros and cons.

This review of the history of welding helmets may briefly guide you through it and occasionally help you understand who has been first involved in producing this protective headwear, which now saves welders from many risks.
