Welding equipment: Equipment category Specific application scope Argon welder Widely used in large, medium and small parts, sheet metal chassis, sheet metal class welding.Small deformation, beautiful welding. Carbon dioxide gas shielded welding machine Widely used in large, medium and small parts welding, greatly improve the welding efficiency Cold welding machine Used for the repair of the out-of-tolerance of precision and small parts Laser welding machine Used for precision welding of micro and small parts Resistance welding machine Used for sheet metal chassis, sheet metal parts spot welding processing Welding quality inspection： Welding meat defects Specific description Spurious welding Spurious welding refers to the welding defects such as unfused and disconnected welds (the weld length required by the process cannot be guaranteed). Air breather Piercing hole on the surfaces of welding spot Crack Cracks appears in the weld. Slag inclusion solid entrainment. Undercut The excess between the weld and the base material is too severe Burning through The base material was burnt through. Splashing Metal liquid fly out and stick to the area of functional and appearance requirements. Over high weld is convex The weld is too big,H values does not allow more than 3mm. Position deviated Weld position is not correct. Coordinate with bad plate butt joint gap is too big.Engineering factor:1.Welding material shall conform to design requires and provisions of relative standards, the certificate of quality and other relevant information shall be checked.
2.Welder shall pass the examination, to check the welder's corresponding welding conditions and the date of assessment.
3.Class I II welds shall be tested for flaw detection and conform to design requires, construction and acceptance specifications. Providing reports of flaw detection on welds.
4.Uniform appearance of the weld seam, smooth transition between welds and welding toe, Cleaning up the welding spatter.
5.I, II class welds shall not exist the defective situation of incompletely filled weld, undercuts, non-shrinkage, and crack, blowholes and arc strike on the surface.301 products foundViewListShowcaseCustomized precision welding machining service of mechanical partsGood quality welding parts in Dalian HongshengDalian Hongsheng provides different types of welding servicesCustomized precision welding parts in Dalian HongshengDalian Hongsheng provide high quality customized welding partsMade in China customized welding partsPrecision customized welding parts in Dalian HongshengPrecision customized welding parts in Dalian HongshengDalian Hongsheng provide high quality welding partsCustomized welding parts in Dalian HongshengProfessional welding service in Dalian HongshengPrecision customized welding parts in Dalian HongshengDalian Hongsheng provide professional made welding partsPrecision welding parts in Dalian HongshengOxy-fuel welding and oxy-fuel cutting are processes that use fuel gases and oxygen to weld or cut metals.Fusion welding is a generic term for welding processes that rely on melting to join materials of similar compositions.Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal.Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics.Customized welding fabrication services in Dalian HongshengDalian Hongsheng provide high quality welding partsPrecision customized welding fabrication service in Dalian HongshengPrecision customized welding parts in Dalian HongshengWelding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics.Arc welding is a type of welding process using an electric arc to create heat to melt and join metals.Precision custom welding parts in Dalian HongshengDalian Hongsheng supply high precision welding partsPrecision customized welding parts provider in ChinaDalian Hongsheng provide OEM made welding metal partsContact us
