MIG Brazing Wire (DIL350)

Copper alloy wire for light gauge drawn steel welding.

MIG BRAZING WIRE DIL 350
DIL 350 wire is special alloy developed as the material for MIG brazing, which is made of copper as the base metal with silicon and manganese, generally named silicon bronze or MIG brazing wire. Our DIL 350 wire is especially applicable for light gauge steel sheet for the automobile industry. The produces very smooth beads finish. DIL 350 wire utilizes the eutectic point of the brazing material in order to reduce the heat distortion of base metals as much as possible. The braze metal melting temperature is very low and bead height is very small. DIL 350 has very good grind ability since the hardness of the DIL 350 is controlled. With attention to the root gap and joint shape, DIL350 is applicable to lapped fillet welding, butt-welding, horizontal fillet welding and edge welding with all welding positions.

FULLY AUTOMATIC WELDING SYSTEM
We, Daishin Industrial Co., Ltd. specialize in the design and manufacture of automatic systems. We have developed a heat distortion correcting system for light gauge steel welding, which has been proved by many results and experiences. Our fully automatic brazing machine using DIL 350 is integrated with a sensor to monitor the teaching locus and to check the orbit correction value, which occurs by welding distortion at the welded area. This system is also available for the correction of precision error while setting up the work piece.
* A robot application is sketched below. DIL 350 can be applied on the robot and N/C machine.
FULLY AUTOMATIC WELDING SYSTEM

1. Argon gas 2. Power supply 3. Wire feeder 4. Robot 5. Welding torch 6. Robot controller
* A multiple arm robot fixed on a ceiling is available besides the above.
MIG BRAZE WELDING METHOD
MIG brazing is one of the joining methods for light gauge steel (SPCC, SS41P, etc.) without melting the base metal using a MIG welder with copper alloy as the wire material wound on a reel. For this welding method, only argon gas is used.
