Abstract


The armored the vehicle bodywork turret attached seat main hand SMAW or semi-automatic gas shielded arc welding , prone to not weld defects such as cracks, holes , practice shows that the use of induction heat source . Stud welding composite heat source is a large diameter screw column and Heavy steel connection effective process method. On the basis of comprehensive analysis of the research status of stud welding technology at home and abroad , the welding torch structure suitable for stud welding of large-diameter composite heat source of the welding torch electromagnetic lifting mechanism , buffering mechanism , height adjustment mechanism , water cooling institutions the study design , calculation select the material of the welding torch in parts developed for large diameter stud welding stud welding gun . In the analysis of domestic and international all-solid-state induction heating technology based on the analysis of the induction Arc Hybrid process and heating characteristics of a the compound heat source induction heating coil design of composite heat source screw diameter of 10 ~ 30mm studs the column soldering, induction heating time of about 10-30s, and the induction heating process in the cooling system of the optimization program . Design and development , torch, induction loop and its clamping device , protection device of the welding process , welding drive device , optimized integration the arcing 3000A stud welder 29KW solid state IGBT induction power supply and system controller , manual composite heat source stud welding principle prototype . According to the needs of the development and production of heavy vehicles to the MOTOMAN-ES165N robot the attached seat movement and control device , designed to fully automated robotic stud welding system , the system automatically jacket automatically taken with Seat , attached to seat automatically sent other functions to complete the drawings of the entire composite heat source stud welding process automation , intelligent device . Self-developed large diameter stud welding gun welding test results show that the torch with a good performance , good weld forming welding , heat-affected zone is not overheating , welding cracks and other defects , compared with the German stud welding gun strength There are no significant gaps.
