G.J. Oliver's welders are highly skilled, experienced and qualified to A.S.M.E, PED, AWS and MIL Spec standards.

G.J. Oliver has multiple welding engineers on staff and currently has over 150 qualified welding procedures incorporating manual and semi-automatic welding processes including GTAW, SMAW, GMAW, FCAW, and SAW processes. As a result, we are able to produce fabrications from wide diversity of materials such as carbon steels (including low temperature carbon steels), various stainless steels including: austenitic, martensitic, and duplex stainless steels, high alloy materials such as chrome-moly and inconel, aluminum and number of other specialty metals. G.J. Oliver also provides all required nondestructive testing (NDT) with a team of in-house inspectors and outside agencies to cover NDT including positive material identification (PMI), hydro testing, hardness testing, radiographic testing (RT), liquid penetrant testing (PT), magnetic particle testing (MT), ultrasonic testing (UT), and many more. With our Project Management, Engineering and Quality Assurance Staff we constantly strive to excel in providing on-time deliveries with the highest quality. G.J. Oliver, Inc. is a “one stop shop” when it comes to your fabrications needs. Within our 22 acre facility, located in Phillipsburg, NJ, we have the expertise know how, tooling and equipment to cut, form, roll, weld, stress relieving heat treat, machine, and coat your standard or custom fabrications.
