All-State
Super Join-M® Specially
Designed for Build-up Prior to Hardfacing AC
or DC Reverse Polarity General
Characteristics Smooth
weld characteristics. Specially designed for severe impact and multi-pass build-ups
on both manganese and
iron base alloys. Ideal for joining dissimilar and welding problem steels. Resistant
to corrosion from water, steam
and mild corrosives at temperatures up to 512°F (267°C).
Typical Applications
Repair and build-up railroad tracks,
frogs and switches. For mill, quarry and gravel plant crushing hammers.
Also for attaching dipper teeth and
welding the roller circle to ring gear in excavators. Qualities
Tensile strength
—up to 100,000 psi (70.32 kgs/mm2)
Hardness
—200
BrineIl as welded Work
Hardens —300-400
Brinell depending on base metal Procedures
Clean weld area. Use All-State®
Chamfer Rod to remove work-hardened and damaged metal. Do not preheat
manganese steel. Weld in short lengths
(3 to 4 inches (75mm to 100mm) using skip and backstepping welding
techniques. Base metal should never
reach 600°F (316°C) 1/2" (12.7mm) away from weld area. Peen deposits
to both shape
and reduce stresses. Remove slag between passes. Allow to cool slowly.
Diameters and Recommended Amperages
1/8" (3.2mm)—90-120
5/32" (4.0mm)—120-160
3/16" (4.8mm)—160-190
