影響焊接性的主要因素

Main factors affecting weldability
1.材料因素;料是指用于制造結構的金屬材料及焊接所消耗的材料。前者稱為母材或基本金屬,即被焊金屬;后者稱為焊接材料,包括焊絲、焊劑、保護氣體等。其中化學成分(包括雜質的分布與含量)是主要的影響因素。在焊接結構中,絕大多數常用的金屬材料是鋼材。碳對鋼的焊接性影響非常大。含碳量越高焊接性越差。
1. Material factors; Materials refer to the metal materials used to manufacture structures and the materials consumed by welding. The former is called base metal or base metal, that is, the metal to be welded; The latter is called welding material, including welding wire, flux, shielding gas, etc. The chemical composition (including the distribution and content of impurities) is the main influencing factor. In welded structures, the vast majority of commonly used metal materials are steel. Carbon has a great influence on the weldability of steel. The higher the carbon content, the worse the weldability.
2.設計因素;設計因素是指焊接結構在使用不但受到材料的影響,而且在很大程度上還受到結構形式的影響。
2. Design factors; Design factor refers to that the use of welded structure is not only affected by materials, but also affected by structural form to a great extent.
3.工藝因素:工藝因素包括焊接方法(如電弧焊、埋弧焊、氣體保護焊等)、焊接工藝(包括焊接規范參數、焊接材料、預熱、裝配焊接順序)和焊后熱處理等。
3. Process factors: process factors include welding methods (such as arc welding, submerged arc welding, gas shielded welding, etc.), welding process (including welding specification parameters, welding materials, preheating, assembly and welding sequence), post weld heat treatment, etc.
4.使用因素:使用因素指焊接結構的工作溫度、負荷條件和工作環境(化工區、沿海及腐蝕介質等)。一般來講,環境溫度越低,鋼結構越易發生脆性破壞。
4. Use factors: use factors refer to the working temperature, load conditions and working environment of the welded structure (chemical area, coastal and corrosive medium, etc.). Generally speaking, the lower the ambient temperature is, the more vulnerable the steel structure is to brittle failure.
