1. Welded square tube yintsimbi yesikwere ityhubhu enomngxuma, ekwabizwa ngokuba yintsimbi epholileyo.Yenziwa ngokugoba okubandayo kunye ne-high-frequency welding emva komgca oshushu oqengqelekayo okanye obandayo okanye i-coil njengentsimbi engenanto eMilo enemilo enqamlezayo kunye nobukhulu.
Ukongeza ukutyeba kodonga lwetyhubhu yesikwere esityebileyo, ubungakanani bembombo kunye nohlangothi oluthe tyaba lufikelela okanye lugqithise kwinqanaba lokumelana ne-welded square-formed square tube.Ubungakanani be-angle ye-R ngokuqhelekileyo phakathi kwamaxesha ama-2 kunye namaxesha ama-3 ubukhulu bodonga..Ngokuhambelana neemfuno zabathengi, sinokuphinda sivelise i-R-angle square tubes zobukhulu obufunwa ngabathengi;
2. Ityhubhu yesikwere engenamthungo yintsimbi ende enecandelo elinomngxuma kwaye akukho malungu kwiperiphery.Yityhubhu yesikwere eyenziwe ngokukhupha ityhubhu engenamthungo ngamacala ama-4 obumba.Ityhubhu yesikwere inecandelo elingenanto kwaye isetyenziswe ngobuninzi.Isetyenziselwa ukuthutha ulwelo, inkxaso ye-hydraulic, ukwakhiwa komatshini, uxinzelelo oluphakathi kunye noluphantsi, ityhubhu yebhoyila yoxinzelelo oluphezulu, ityhubhu yokutshintshiselana ngobushushu, igesi, i-petroleum kunye namanye amashishini.Yomelele kune welding kwaye ayiyi kuqhekeka.
