Weldability Testing

Precision Components offers comprehensive base material weldability testing utilizing a diverse selection of welding processes and parameters. Weldability testing includes simple arc characteristic evaluations, metallographic analysis and destructive testing.

Welding Process Selection

As part of developing unique in-house manufacturing capabilities, PCC's welding process expertise includes such applications as:
  • Narrow groove submerged arc welding of carbon and stainless steels in thicknesses up to 24 inches with 2° to 8° included angles
  • Automatic tube-to-tubesheet welding of Titanium and Nickel based alloys
  • Narrow groove automatic gas tungsten arc welding of Titanium and Nickel based alloys using video vision capabilities
  • Remote pipe I.D. welding with direct view vision capabilities
  • Spiral cladding of bores down to 1 inch I.D.
  • Automatic GMA twin arc welding of stainless steel

Standard welding processes, as well as advanced joining processes (i.e. laser, electron beam, diffusion) are evaluated for their cost effectiveness of application.

Welding Procedure Development

PCC's in-house Welding Development Laboratory offers complete welding procedure development and qualification capabilities. PCC can select, develop and qualify welding procedures to meet a range of customer needs from seal welding of material only a few thousandths of an inch thick to narrow groove welding heavy wall forgings.

Welder Training Qualification

PCC can train and qualify welders in accordance with commercial and military welding specifications. PCC can provide welder training and qualification for your firm from classroom instruction of process theory to hands-on training with prototypical mockups.
