Welding & Fabrication Services

Welded Materials

Prime Machines welding services include welding of the following materials mild steel, alloyed steel, stainless steels, aluminum, titanium, bonzes and cast iron.

Welding Methods

Prime Machines welding services include welding with the following methods: Arc welding, Flux-cored welding, Gas Tungsten-Arc Welding, Metal Inert Gas (MIG), Plasma arc welding, Shielded-Metal arc, Submerged arc.

Welding services

Prime Machine welding services include providing welders to work on your projects under your direction or providing complete engineered welding methods.

The experienced fabrication technicians are trained in manual and automated processes. This assures the highest quality in repetitive parts, and the most common sense approach to unique projects.

The technicians are skilled and certified holding ASME and AWS welding code certificates.  They are also knowledgeable with exotic materials and processes.  The capability of large fabrication and large machining at our facilities create a unique synergy to provide real value to our customers.
