Welding Beam Offset. 11 Schematic for illustration of beam offset position in electron beam welding of Ti55TA15 weld. Laser beam power of 576 W defocusing distance of 5 mm welding speed of 650 mmmin.
Length of a fillet weld shall be at least four times the nominal size or the effective size of the weld shall be considered not to exceed 25 of its effective length. Investigated the weld strength in the offset range 03 to 15 mm and the optimum range of 02 to 10 mm for steel and copper respectively. Parameters used in laser beam offset welding of dissimilar MoTi joint.
In the AgFe18Cr8Ni weld a layer of about 20 m thick of steel.
The alloy contains the beta-isomorphous elements V and Mo and the sluggish beta-eutec-toid elemen t Cr a levels which depress. The effects of laser beam offset on the laser dissimilar joint of pure molybdenum to pure titanium were analyzed in terms of microstructure chemical composition microhardness and tensile behavior. This offset shows on the reference line as well. Offset beams in T and Z shapes are now easily produced to fit exact geometry load and length requirements.
