With six MIG and TIG welding stations, Pen Manufacturing has one the highest in-house capabilities out of all welders in Southern California area for; aluminum, carbon steel, stainless steel, cast iron, and bronze welding.


Welding Certifications & Capabilities

Pen Manufacturing holds the following certifications:

  • AWS D1.1 Structural Steel
  • AWS D1.2 Aluminum
  • AWS D1.6 Stainless Steel

MIG weldingOver the last couple of years Pen Manufacturing has worked with customers to develop project specific Weld Procedure Specifications (WPS) and subsequently certified some of the personnel to those WPS's.

Pen Manufacturing has the experience and the capabilities to handle stock up to 40' long, 12' square, with a minimum thickness of .0030". MIG (Metal Inert Gas) welding is an automatic or semi-automatic welding method that utilizes a wire electrode along with a shielding gas, sometimes referred to as a consumable arc, which is fed through a welding gun. Several power sources can be used for MIG welding, including direct current (DC) - constant voltage, which is the most common, as well as constant current and alternating current power sources. There are four commonly-recognized techniques of metal transfer in MIG welding – pulsed spray, spray, short-circuiting and globular.

What is MIG Welding?

MIG weldingMIG welding was initially implemented in the 1940s, specifically for welding non-ferrous metals such as aluminum. MIG welding soon became used for steel as well, since it permitted a shorter welding time compared to other traditional welding methods. Steel MIG welding became even more commonplace when the use of semi-inert gases (such as carbon dioxide) was implemented. Additional improvements in the MIG welding process through the 1950s and 1960s resulted in MIG welding becoming one of the most popular, heavily used industrial manufacturing processes. Advantages of MIG welding include:

  • Adaptable to robotic automation
  • Relatively simple to learn
  • Versatile
  • Relative ease of use
  • MIG welds can be completed quickly (speed)
