Muaj ntau hom hluav taws xob tsis kam vuam (erw), thiab muaj peb hom vuam, seam vuam, taub qab vuam thiab projection vuam.

Ua ntej, qhov chaw vuam
Spot welding yog ib txoj kev siv hluav taws xob tiv thaiv vuam nyob rau hauv uas lub vuam yog sib sau ua ke rau hauv ib lub puab tsaig sib koom tes thiab nias ntawm ob kab hluav taws xob kom yaj lub hauv paus hlau los ntawm hluav taws xob los ua ib qho kev sib koom ua ke.Spot welding feem ntau yog siv rau nyias phaj vuam.

Spot welding txheej txheem:
1. Preloading kom ntseeg tau tias kev sib cuag zoo nrog lub workpiece.
2. Fais fab rau, kom cov weld yog tsim rau hauv ib tug nugget thiab ib lub nplhaib yas.
3. Fais fab-tawm forging, kom lub nugget txias thiab crystallizes nyob rau hauv lub siab, thiab tsim ib tug welded sib koom tes nrog ntom qauv, tsis muaj shrinkage qhov thiab tawg.

Thib ob, seam vuam
Seam welding feem ntau yog siv rau vuam welds uas yog ib txwm tsis tu ncua thiab xav tau kev sib khi.Lub thickness ntawm qhov sib koom ua ke feem ntau tsawg dua 3 hli.

Thib peb, taub qab vuam
Butt welding yog ib txoj hauv kev ua haujlwm vuam uas muaj 35Crmo alloy raj yog welded raws tag nrho qhov chaw sib cuag.

Plaub, projection welding
Projection welding yog ib qho txawv ntawm qhov chaw vuam;muaj prefabricated pob ntawm ib lub workpiece, thiab ib los yog ntau tshaj nuggets tuaj yeem tsim ntawm kev sib koom ua ke ntawm ib lub sijhawm.
