Domite® WELDING DETAILS

RECOMMENDED WELDING PROCEDURES

READ ALL PROCEDURES COMPLETELY!

You should always use a soft-face hammer and ANSI-approved (Z87.1) eye protection during cutting and bending procedures. (Chocky Bars ony )

1. Ensure that the surface to which the Domite° will be attached to, is as flat as possible and the area to be welded is clean.

2. Clamp and tack weld Domite® into position.

3. Stitch weld, laying 50mm max length on each run, alternating ends or sides to minimise heat input. Do not deposit weld within 2mm from the joint line between Domite and steel backing plate (Fig. 1).

4. DO NOT WELD CONTINUOUSLY Continuous welding may cause warpage, delamination and cracking. Use thermal crayons to check temperature,

maximum allowed 200°C.

5. If a complete peripheral weld is required, use stitch weld method as per step 3.

6. WELDING RODS    WE RECOMMEND LOW HYDROGEN WELD RODS OR GAS COVERED CORED WIRE.

                                       Gas shielded solid MIG wire     -1.2mm dia. max

                                       Flux cored wire                       - 1 .6 mm dia. max. to ASTM/AWS

                                                                                      A5.18 classification ER705-6

Low hydrogen electrode-            3.25 mm dia. max. to ASTM/AWS

  A5.1 classification E7016-1H8 or  E7018-1H4

WELDING PROCEDURE OVERVIEW

1. READ PROCEDURES COMPLETELY

2. TACK WELD INTO POSITION

3. STITCH WELD WITH (50mm) MAX. LENGTH ON EACH RUN

4. MAINTAIN 2MM GAP BETWEEN WELD AND JOINT LINE

CAUTION ! TOO MUCH HEAT INPUT MAY CAUSE CRACKING AND SEPARATION
