Cutting and Forming
Caution: Induction hardening process imparts internal stresses in the pipe wall. Pipe should never be cut lengthwise. To prevent personal injury or property damage, all cutting and welding should be done with caution.
• Plasma arc cutting is recommended however abrasive disc saws and oxyfuel can be used
• SLS600 can only be formed during the induction hardening process
• SLS600 can only be custom formed in standard pipe sizes 3” to 16” dia.
• Radius options include a min. 20” centerline radius or 3D (3 x diameter) up to 96” max. centerline radius
• Precision wall thickness is maintained through special induction bending
Joint Preparation
• Remove all slag and discolored material after cutting in weld area
• Inspect surfaces to be welded – avoid welding areas that have tears, cracks and other discontinuities
• Clean joint area at least 1/2” (12.7 mm) from welding joint; remove all loose scale, rust, moisture, grease, etc.
Fit Up
• Bring parts into as close contact as practical; root opening should not exceed 3/16” (4.76 mm)
• For separations greater than 1/16” (1.58 mm), increase leg of fillet weld by the amount of the opening.
Welding
• If ambient temperature of parts are below 70º F (21º C), preheat weld zone and 6” (152.4 mm) of adjacent material to 100º F (38º C)
• Place welds on exterior of pipe
• Keep weld beads as small as possible; length should not exceed 5 to 6 inches (127 mm to 152.4 mm)
• Allow pipe to cool before applying additional beads. Do not exceed 450º F
• Use stringer beads; avoid weaving beads.
• Use low hydrogen electrodes, E-7018 series
• Weld using multiple passes - five to six passes for 3/8” (9.5 mm) fillet welds, ten to twelve passes for 1/2” (12.7 mm) fillet welds
