1. Air Hole sy Slag Inspion

b. Ny tsorakazo sy ny tsipìka alkaline dia ampiasaina ary maina tsara.
c. DC Reverse Connection sy ny fitaovam-piadiana arc fohy dia hamboarina.

E. Ny fitrandramam-borona dia ho tanterahana manokana.

Crackle

a. Mampihena ny votoatin'ny singa manimba toy ny solifara sy ny phosphorus, ary ny weld misy fitaovana misy votoaty karbonina ambany.
b. Certain alloy elements are added to reduce columnar crystals and segregation. For example, aluminum and iron can refine grains.

d. Welding specifications shall be reasonably selected, and preheating and afterheating shall be adopted to reduce the cooling rate.
e. Manara-maso ny filaharana amin'ny fivoriambe mety hampihena ny fihenjanana.

a. Pay attention to the strengthening effect of metallurgical elements and their influence on reheat cracks.
b. Reasonably preheat or use afterheat to control the cooling rate.
c. Mampihena ny adin-tsaina sisa tavela hisorohana ny fifantohana amin'ny adin-tsaina.
d. During tempering, avoid the sensitive temperature zone of reheat cracks or shorten the residence time in this temperature zone.

a. Ny karazana hidradradradrana ambany sy ny tsorakazo ao Hydrogen.
b. The preheating temperature shall be increased, the post heating measures shall be taken, and the interpass temperature shall not be less than the preheating temperature. The reasonable welding specification shall be selected to avoid brittle and hard structures in the weld.
c. Safidio ny filaharana mitombina mandanjalanja mba hampihenana ny fanalavana sy ny fientanentanana.
d. Mitarika ny fitsaboana ny hidrogen amin'ny fotoana mafana ara-potoana aorian'ny fambolena
