If due consideration is given to the general rules for welding, this steel is weldable both manually and automatically. To prevent cold cracking in the welded joints only welding consumables giving welds of very low hydrogen content should be used.

 Preheating is not generally necessary for welding with austenitic filler metals.

 For highly stressed weld seams, welded with ferritic filler metals, preheating should in general be used for thicknesses stated in STAHL-EISEN-Werkstoffblatt 088. The preheat temperature level for welding depends on the plate thickness and the residual stress state of the structure. The working temperature should not go beyond 250 °C (482 °F).

 The wear resistance of components fabricated of XAR ^® 400 may be increased with the aid of wear resistant layers deposited by means of welding or metal spraying.

如果考慮到焊接的一般的要求，手工焊接和自動焊接都適合這種材料是。為了避免在對接焊接處發生冷裂發

生，很重要的一條要注意就是焊材選用含氫量很低的焊材。

 對已奧氏體焊材，XAR® 400 耐磨鋼板預熱一般情況下是不需要的。

 對于用鐵素體焊材焊接有高應力的焊縫，一般情況下在STAHL-EISEN-Werkstoffblatt 088列出的厚度的鋼板

應該要預熱。溫度取決對于鋼板的厚度和結構的殘余應力。 預熱溫度不應該高于250 °C。

 由蒂森克虜伯耐磨鋼 XAR400 板制作的構件的耐磨性，有可能由于焊接時或金屬噴涂時耐磨層的沉積的幫助而提高。
