MoldStar®150 & MoldStar®90
Welding Guidelines

Feedback from material users that have welded MoldStar®150 and MoldStar®90 indicate that Tig welding with Argon is the preferred shielding gas for Tool and Die type welding. Blends of Argon with Carbon Dioxide are also successful.

Micro and Laser Welding are also excellent choices in combination with our NEW small diameter rod (see below)

Brazing, gas welding and silver soldering are not recommended and did not show much success or promise.

Small parts do not need to be preheated, other than to warm the part enough to dry them of environmental humidity.

Larger blocks should be preheated to between 400 and 500 degrees F. This procedure is done primarily as a measure to keep the block itself from being a heat sink. If this measure is not taken, the cooler mass of the block will pull heat needed to melt away from the area of concentration.

During preheating procedures, blocks should not be left in room air at elevated temperatures longer than actually needed to elevate to desired temperature. If blocks are left to preheat for excessive periods of time, copper oxides will form on the surfaces of blocks which is potential contamination to weld area.

If oxides form they should be cleaned from the immediate weld area, prior to welding procedure, with a wire brush or other non destructive cleaning method.

WELDROD: to be used for normal repairs is MoldStar® weld wire.

Available for Tig Welding:

  • 1/16 diameter x 36" bare wire electrode sold by the pound
  • .047 diameter coil stock sold by the pound or lineally.

NEW FOR LASER AND MICRO TIG WELDING

.011", .015" & .027" diameter wire for LASER and Micro WELDING. SOLD IN LENGTHS by the GRAM

MoldStar®  weld rod available Exclusively from Performance Alloys.

Our NEW MoldStar® weldrod has shown to be the rod of choice to repair all MoldStar® alloys, Copper Nickel alloys, and Beryllium Copper alloys. HARDNESS level is reasonably close to parent material where applied, Great COLOR MATCH with no sink at edges of weld zone.

Alternate welded materials:

  • 420 Stainless, for high hardness
  • 17-4PH Stainless, for hardness
