求翻译：海洋平台用钢主要是厚板，一般都在20mm以上，普通的焊条电弧焊，气体保护焊已经不能满足厚板焊接的要求，而埋弧焊恰恰在厚板焊接方面有较多优势。是什么意思？

Offshore platform steel slab, usually 20mm or more in common SMAW, gas shielded arc welding has been unable to meet the requirements of thick plate welding while submerged arc precisely in the thick plate welding have more advantages.

Marine platform is mainly made of steel plates, are in general more than 20 mm, and the normal arc welding, gas welding rod welding protection plate has been unable to meet the requirements, and welding arc welding is precisely in thick plate welding may have more advantages.

The sea platform with the steel mainly is a thick plate, all above 20mm, the ordinary welding rod arc welding, the shielded welding already could not satisfy the thick plate welding generally the request, but the submerged-arc welding exactly had many superiority in the thick plate welding aspect.

Was mainly thick plates of steel for offshore platforms, are generally more than 20mm, ordinary arc welding, gas metal arc welding can no longer meet the requirements of thick plate welding, and submerged arc welding in welding for thick plate with more advantages.
