Tufmetal II Welding Recommendations

We have found the following procedure to be most successful when welding Pacific Alloy Castings Tufmetal II (ASTM A532 Class III Type A) material to a base material of Tl or Plow Steel for ripper points.

Directions:

Place chrome casting on flat non-worn base boot slab. If surface is not flat and smooth, take appropriate actions to grind/finish surfaces properly.

Wire feed (MIG):

Lincoln Ready Reel .035 to.045 diameter rod 70S series.

Lincoln part number for.045 is C045L50 Other equivalents are also acceptable.

Amperage:

Use as low amperage as possible (90-120 amps)

Cooling: Avoid thermal shocks (i.e. cold floors, drafts, water) It is recommended that welded parts be placed for slow cooling in a dry sand bed or ashes with at least 6 inch base.

Cooling

Avoid thermal shocks (i.e. cold floors, drafts, water) It is recommended that welded parts be placed for slow cooling in a dry sand bed or ashes with at least 6 inch base.

 

Note: Minor cracks may appear along the edges of the casting after welding. These are not detrimental to the weld or the effectiveness of the casting wearability. This is not a structural weld but merely a bonding process.

PRE-HEAT AND AFTER-WELD HEAT TREATMENT

Contrary to most procedures we have found it not necessary to do any preheating or heat treatment. Should you encounter conditions which may require heating, please consult the factory for recommendations.
