Welding Metal Bars. When welding on bars that are already embedded in concrete allowances must be made for thermal expansion of the steel to prevent spalling or cracking of concrete or destruction of the bond between the concrete and steel. For using it for Structural purpose you need to weld 2 scrap bars by lapping them at minimum 15D and welding those bars at 5D on alternate side by tacking or stitching You can use normal welding rods for this type of work ensure the weld is small tacks only do not over-weld which cause steel to loose its properties.

Steel welding grades are developed to guarantee coherent chemical and mechanical properties between the welded joint and the base metal. Weld metal shall penetrate all layers of deck material at end laps and shall have good fusion to the supporting members.
When welding on bars that are already embedded in concrete allowances must be made for thermal expansion of the steel to prevent spalling or cracking of concrete or destruction of the bond between the concrete and steel.
This can be done easily as you only need to put a plain metal bar and clamp it to the weldment. 1 the thickness of the base metal for metal less than 14 in. Welding of reinforcement is an instant solution in many cases whereas welding is not a routine connection process. Choose from thousands of the best stock footage video clips to download.
