Longitudinal Seam Welder - Liburdi.com
The weld’s heat affected zone. The copper backing bar additionally provides the necessary inert gas shielding of the joint using purge gas diffusers. The clamping fingers press down on the component to create a tight fitting and secure weld joint. The welding torch travels in a precise, straight line on a ... Document Retrieval
Weld Backing Tape™ And Weld Purge Tape™
Temporary backing bar To overcome the disadvantages of the integrated backing bar a support can be clamped in place and removed after the joint has been completed. To avoid the possibility of welding the bar to the joint these temporary supports are often water cooled and manufactured from copper. The supports are expensive to ... Access Content

Weld Backing Materials R U C T U R E® - Structuremag.org
Welding against ceramic backing requires training and skills. The welder has to learn to control the arc differently than with steel backing. With steel backing, the weld metal is to fuse to the backing bar so the arc is directed to the front of the puddle. With nonferrous backing, the arc has to stay in the puddle or ... Read Here
