PHYSICAL ARC STUD WELDING TESTING with ceramic ferrule
BEND TEST: By striking the stud with a hammer, or by sliding a length of pipe or tube over the stud, the stud can be bent a minimum of 30 degree away from its axis, or until failure occurs. Satisfactorily welded studs should exhibit a complete 90 degree bend without failure.
TORQUE TEST : The stud may be torqued with conventional torque testing equipment by applying torque until a predetermined torque or proof load is reached or until failure occurs.
TENSILE TEST : The stud may be tested with conventional tensile testing equipment until a
predetermined load is reached or failure occurs.
OTHER : The stud and weld can be submitted to other conventional forms of destructive or non
-destructive testing as specifications may required.
We can make ceramic ferrule for stud welding according to your drawing.Also our ceramic ferrule has passed above test.(normally with shear connector)
