Pali mitundu yambiri ya kuwotcherera kukana kwamagetsi (erw), ndipo pali mitundu itatu ya kuwotcherera, kuwotcherera kwa msoko, kuwotcherera matako ndi kuwotcherera projekiti.

Choyamba, kuwotcherera malo
Spot kuwotcherera ndi njira yowotcherera kukana kwamagetsi komwe kuwotcherera kumasonkhanitsidwa mu mgwirizano wa lap ndikupanikizidwa pakati pa ma elekitirodi awiri a columnar kusungunula chitsulo choyambira ndi kukana kwamagetsi kuti apange cholumikizira cha solder. Spot kuwotcherera makamaka ntchito woonda mbale kuwotcherera.

Njira yowotcherera malo:
1. Preloading kuonetsetsa kukhudzana bwino ndi workpiece.
2. Mphamvu, kotero kuti weld apangidwe kukhala nugget ndi mphete ya pulasitiki.
3. Kuwombera mphamvu, kotero kuti nugget imazizira ndi crystallizes pansi pa kukanikiza, ndipo imapanga mgwirizano wonyezimira wokhala ndi wandiweyani, palibe dzenje la shrinkage ndi ming'alu.

Chachiwiri, kuwotcherera msoko
Kuwotcherera kwa msoko kumagwiritsidwa ntchito kwambiri pakuwotcherera komwe kumakhala kokhazikika komanso komwe kumafunikira kusindikiza. Makulidwe a olowa nthawi zambiri amakhala osakwana 3 mm.

Chachitatu, kuwotcherera matako
Kuwotcherera matako ndi njira yowotcherera yokana momwe chubu cha 35Crmo alloy chimawotcherera pamalo onse olumikizana.

Chachinayi, kuwotcherera projekiti
Kuwotcherera kwa Projection ndi mtundu wa kuwotcherera kwa malo; pali tokhala opangidwa kale pa workpiece, ndipo nuggets imodzi kapena zingapo zikhoza kupangidwa pa olowa pa nthawi.
