AWS Certified Welding
Vista Industrial Products Inc. has a formal training program for the certification of weld operators and visual weld inspectors for the following major AWS Codes as required by our customers:
AWS D1.1 Steel
AWS D1.2 Structural Aluminum
AWS D1.3 Sheet Steel
AWS B2.1 / D1.6 Stainless
AWS D1.1 Steel
VIP shall be AWS certified to TIG weld various thicknesses of round, square, rectangular tubing and many other structural shapes including flat bar, “T” bar, angles, channels, and “I” beams. These requirements are defined by our customers.
Materials include:
- Mild steel
- Structural grade steel
- 4130 chrome-molly alloy
TIG welding process is known as root pass or cover pass which produces an extremely strong weld joint. This is the preferred method for many military applications where extreme strength is required, and where nondestructive testing is part of the work statement.
MIG or GMAW is also covered under this structural weld certification. GMAW is the preferred method for mild steel and structural steel up to ½ inch thick where a standard strength weld joint is required. This produces an excellent structural weld much more quickly than the TIG welding process.
FCAW or shielded flux core method of welding is suitable for both structural steel and mild steel with material thicknesses over ½ inch. The FCAW process generates a very “hot” weld bead and so maintains a very strong weld joint in thicker materials with multiple weld passes.
VIP combines all three of these processes on a single item in order to meet the rigorous requirements of some of our D.O.D customers. We successfully produce the high quality structural units that are not only extremely strong and durable but are also very cosmetic.
AWS D1.2 Structural Aluminum
This code covers the welding requirements for any type structure made from aluminum structural alloys, except for aluminum pressure vessels and fluid-carrying pipe lines. D1.2 includes TIG welding many types of sheet stock in thicknesses that vary from .020 inch to .375 inch in various alloys. The aluminum TIG welding process is used to weld components for the electronic and medical industries such as chassis and cabinets. It can also be used to weld water tight frames for the U.S. Navy. This process produces a very light weight, yet a very strong product, and is highly corrosion resistant after plating.
AWS D1.3 Sheet Steel
This code covers the requirements associated with welding sheet steel having a minimum specified yield point no greater than 80 000 psi (550 MPa). The code requirements cover any welded joint made from the commonly used structural quality low-carbon hot rolled, cold rolled sheet and strip steel with or without zinc coating (galvanized).
D1.3 includes TIG welding thin and thick gauge mild steel sheet, many types of industrial tubing, and structural shapes from .020 to .375 inch thicknesses, and sometimes even thicker!
This process allows for fabrication of a variety of different shapes, sizes, and types of products for the commercial, industrial, medical, and defense industries, while utilizing the least expensive standard or military standard materials.
AWS D1.6 Stainless
This code covers the requirements for welding stainless steel structural assemblies. Codes B2.1 and D1.6 includes TIG welding thin and thick gauge stainless steel sheet in a large variety of square, round, rectangular tubing and industrial shapes. Vista Industrial has the capabilities to TIG weld thicknesses from .022 to .375 inch. A good working knowledge of thermo-dynamics is required to maintain close tolerances with this type of welding, but with the proper methods, a tolerance of +/- .005 can be consistently held on many types of products.
This type of TIG welding is suitable for a large variety of uses especially where a product is required to perform in a corrosive environment. Many stainless products are used extensively in the food preparation and manufacturing, medical, chemical, and defense industries. Some products include many types of holding tanks, pressure vessels, and fluid or gas carrying tubing assemblies which all require this specialized type of welding.
Being AWS certified in numerous categories allows for quality welding fabrication services and can meet necessary welding specifications you may require.
