Tlas'a maemo a batang e tlaase-carbon tšepe tjheseletsa, lebelo tsidifatso ya lenonyello welded, e leng se entseng cracking tšekamelo ea ho eketseha, haholo-holo pele tjheseletsa Heavy meaho kotsing ea ho peperana, ho ke ke ho hlokahala hore ho nka mehato e latelang tshebetso:

1) Ha ho khonehe tlas'a maemo a mocheso o tlaase oa ho khumama, ho lokisoa le ho kopanya li-welds.

2) Preheat, 16Mn seamless tšepe phala tjheseletsa tshebetso ka tieo bolokoa interlayer mocheso ha ea lokela ho oela ka tlas'a mocheso preheating.

3) Hydrogen kapa ultra-low hydrogen welding.

4) The seam eohle e tsoelang pele welding e lokela ho phethoa ho qoba tšitiso.

5) Ha u beha tjheseletsa ho eketsa lebelo la ho tjheseletsa, lebelo la ho tjheseletsa le fokotsa lebelo, ka lebaka la ho eketsa li-welds sebakeng se fapaneng le bolelele, preheated haeba ho hlokahala.

6) E se ke ea etsoa holim'a motheo oa arc groove ntle le tlhoko ea ho tlatsa crater ha e timela.
