*Water
Hardening AC or
DC Reverse Polarity Electrode All-State®
Water Hardening Electrodes are designed for welding the straight carbon and carbon-vanadium
types of tool
steels. Recommended for welding of trimming tools for cold and hot work, cutting
and bending tools, flanging cutting
tools, punches, shear knives, deep drawing and drawing tools. Also for facing
of gear teeth or cams that will
be flame-hardened and water quenched. Properties
of Weld Metal The
weld deposit is a carbon-vanadium type. “As-welded” hardness is approximately
48-52 Rc; can be annealed and
reheat-treated, drawn or tempered to a degree of hardness. Use on AlSI types W-1
and W-2 (low alloyed and unalloyed
water hardening tool steel grades). Heat
Treatment Anneal
1425°-1450°F (774°-788°C). Harden 1425°-1500°F (774°-816°C)
and water quench. Draw 275°-450°F (135°-232°C).
Procedure Follow
recommended welding procedure on pages 2 and 3 carefully, especially preheating.
Do not exceed maximum
draw-range temperature during welding. Minimum preheat: 275°F (135°C).
Maximum preheat: 450°F (232°C).
Postheating or Tempering
Temper to desired hardness or toughness
towithstand condition to which unit will be subjected. Diameters
and Recommended Amperages 3/32"
(2.4mm)—60-90 1/8"
(3.2mm)—75-125 5/32"
(4.0mm)—100-150
