Advanced Stainless Steel Welding Services

Anderson Dahlen is a certified ASME pressure vessel manufacturer. We hold the U, R, and UM stamps.

Many of the projects we take on also have special stainless steel finishing requirements. We have a full-service metal finishing department capable of producing a variety of finishes on stainless weldments. We can produce a sanitary finish on stainless weldments that meet the USDA standards of a 32ra (#4 finish), and we can meet the BPE standard of 8 ra (mirror finish) as well. Our team is proficient in MIG, TIG, submerged arc, and plasma arc welding processes across a wide range of material thickness, configurations, and welding codes.

Welding Procedures for All Types of Projects

From straight-forward in-position fillet and butt welds to complex out-of-position welding, complete joint penetration (CJP) welds, radiographed joint requirements, subharmonic welding, or PED certifications, Anderson Dahlen knows how to meet your most demanding welding expectations.

We often qualify new welding procedures for our customers and have qualified procedures for a wide variety of materials including but not limited to carbon steel, aluminum alloys, stainless steel, other high nickel alloys, and additional exotic materials.
