To obtain radius of Force from weld centre of gravity A = 27 =mm Moment M = P r = = 2 6 J u = [ b d 4 6b 2 d 2] /12 b d = 1 6 From Table It is necessary to locate the point subject to the highest shear stress For a weld subject to only torsion this would be simply at the point furthest from the COG LIZARD is a portable programmable welding carriage designed to produce high quality welds using MIG/MAG welding torches Friction drive and control loop feedback mechanism provide speed stabilization in all positions A very important optional feature of LIZARD is oscillation attachment This is a list of welding processes separated into their respective associated N reference numbers second column are specified in ISO in the European Union published as EN ISO The Track Welding Carriage With Oscillator is a track welding carriage designed to produce butt and fillet welds with or without oscillation The carriage can work in PA flat PB horizontal vertical PC horizontal PD overhead horizontal vertical PE overhead PF vertical up and PG vertical down welding positions In such cases one should get back to the designer Failing this as a rule of thumb at least two passes should be deposited with a minimum leg length of 6mm 1/4in considering that the first run is likely to be defective International standards do not generally provide requirements or guidance on minimum fillet weld sizes Sprinkler calculator finds the nozzle discharge flow rate for a given diameter and pressure or the diameter size for a given pressure and flow rate Apr 25 The labor and overhead portion of the actual cost of welding is generally between 60 percent to 70 percent of the total cost So selecting an electrode that improves productivity by increasing deposition rates is far more important that selecting an electrode with a lower cost • Standard torch holder for welding torches with diameters of 5/8" – 7/8" 16 22 mm optional large holder for diameters up to 1 3/8" 35 mm • Precise cross slide torch adjustment • Multifunctional LED display and 2 function buttons for welding pattern programming
