焊接工藝評(píng)定的基本要求
Basic requirements for welding process buation
1. 凡施焊單位首次采用的鋼種、焊接材料和焊接方法必須進(jìn)行焊接工藝評(píng)定。
1. welding procedure qualification must be carried out for all kinds of steel, welding materials and welding bs adopted for the first time.
2. 首先由具有一定專業(yè)知識(shí)有相當(dāng)實(shí)踐經(jīng)驗(yàn)焊接工藝人員，根據(jù)鋼材的焊接性試驗(yàn)，結(jié)合產(chǎn)品設(shè)計(jì)要求和工藝條件來制定焊接工藝評(píng)定指導(dǎo)書進(jìn)行試件的焊接工藝評(píng)定，工藝評(píng)定的基礎(chǔ)是鋼材的焊接性能試驗(yàn)，以可靠的鋼材焊接性能試驗(yàn)為依據(jù)，應(yīng)在工程焊接之前來完成。
2. first, the welding technicians with certain professional knowledge have considerable practical experience. According to the weldability test of the steel, the welding process buation guide is made according to the product design requirements and the technological conditions. The basis of the process buation is the welding perbance test of the steel, and the reliable steel welding is used. According to the perbance test, it should be completed before welding.
3. 工藝評(píng)定的焊接試件應(yīng)由施焊單位的持證的焊接人員按照焊接工藝指導(dǎo)書的要求進(jìn)行焊接。
3. the welding specimen for process qualification shall be welded by the welding personnel holding the welding unit according to the requirements of the welding procedure instruction.
4. 焊接工藝評(píng)定所選用的板型鋼材、管材、焊材、接頭形式等應(yīng)與工程實(shí)際相類同，所用設(shè)備、儀表應(yīng)處于正常工作狀態(tài)。
4. the plate type steel, pipe material, welding material and joint b selected for welding process buation should be similar to the engineering practice, and the equipment and instrument used should be in normal working condition.
5. 完成的焊接工藝試件應(yīng)經(jīng)外觀、無損檢測(cè)、機(jī)械性能、金相等項(xiàng)內(nèi)容檢查。將實(shí)際施焊參數(shù)記錄和各項(xiàng)檢驗(yàn)資料整理完成的焊接工藝評(píng)定報(bào)告，由施焊單位技術(shù)負(fù)責(zé)人批準(zhǔn)后編制焊接作業(yè)指導(dǎo)書進(jìn)行實(shí)施。
5. the completed welding process specimens shall be inspected through appearance, nondestructive testing, mechanical properties and bllographic examination. The welding process buation report is completed by the actual welding beter records and various inspection data. The welding operation guidance book is compiled by the welding unit technical officer.
