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.

如果考虑到焊接的一般的要求，手工焊接和自动焊接都适合这种材料是。为了避免在对接焊接处发生冷裂发

生，很重要的一条要注意就是焊材选用含氢量很低的焊材。

 对已奥氏体焊材，XAR® 400 耐磨钢板预热一般情况下是不需要的。

 对于用铁素体焊材焊接有高应力的焊缝，一般情况下在STAHL-EISEN-Werkstoffblatt 088列出的厚度的钢板

应该要预热。温度取决对于钢板的厚度和结构的残余应力。 预热温度不应该高于250 °C。

 由蒂森克虏伯耐磨钢 XAR400 板制作的构件的耐磨性，有可能由于焊接时或金属喷涂时耐磨层的沉积的帮助而提高。
