There are thousands of weld spots in one car. The quality of these weld spots can directly affect the properties of car. Currently, the Spot welding and Laser tailor welded blanks are the main Welding manners. 5.2.1 点焊技术 (spot welding) 点焊是焊件装配成搭接接头，并压紧在两电极之间，利用电阻热熔化母材金属，形成焊点的电阻焊焊接方法。点焊过程通常有 3 个彼此衔接的阶段：焊件在电极间预先压紧；通电后把焊接区加热到一定温度；在电极压力作用下冷却。点焊时由于一定直径电极的加压，使被焊工件变形，且仅在焊接区紧密接触形成电流通道，而其他部分不构成电流通道，从而在焊接区域得到极高的电流密度。 Spot welding belongs to the electrical resistance welding method which uses electrical resistance to heat the base metal to form the welded joints which usually adopt the lap joints. Generally speaking, there are three continuous phases during the spot welding process. The first is to hold specimen together between two electrodes; the second process is to heat the welding area to certain temperature range by electrical circuit; the third process is to cool the specimen under the pressure of electrode force. During the spot welding process, the specimen is deformed under the pressure of electrodes with certain diameters and formed the electrical circuit only in the welded area. As a result, there is a high current density in the welded area. 44 Cold Rolled Automotive Steel Sheets Chapter 5 Use Technology of Automotive Sheets / 使用技术 5.2.2 点焊的影响因素（Factors of the Spot welding）电极压力、电极形状及材料焊接电流、焊接时间镀层种类、镀层厚度、钢板厚度 Electrode force, electrode shape and materials Welding current and welding time Coating type, thickness of coating and steel sheets 点焊示意图 The scheme of spot welding 5.2.3 激光拼焊 (Laser tailor welded blanks) 激光拼焊是将不同厚度或不同材质及不同表面状态的钢材焊接在一起，在冲压制造后，与其他零件一起总装成汽车整车。拼焊板已被广泛的应用于车身部位，ULSAB( 世界轻质钢制车身协会 ) 的最新研究结果表明 : 最新型的钢制车身结构中， 50% 采用了拼焊板制造。 Laser tailor welded blanks are a welding of different thickness or different materials or different surface states of steel jointed together.

Since 2009, it has built and improved its documentation quality system according to ISO9001 standard requirements in view of the actual situation of iron and steel industry and it was awarded with ISO9001 certification. In addition, it passed the ISO/TS16949:2008 standard certification in 2011 and ISO14001:2004 + Cor.:2009 standard certification in 2012. With the implementation of ISO9001, ISO/TS16049 and ISO14001 standards, Shougang Jingtang Steel’s quality system construction and operation kept progressing towards deeper levels. Also, the quality policies and targets were pushed forward to a deep degree. It is also deeply enhanced that the ability for continuous improvement, prevention of defects, as well as reduction of variation difference and waste. The strict documentation quality system established according to the ISO/TS16949 standard fitted to the requirements for quality management systems of different automobile makers in the global automobile industry. It greatly enriches the through-going quality management in the aspects such as allowing the quality management by laws, highlighting eight principles for quality management, laying weight on employee inspiration and sufficient authorization, caring working efficiency and quality cost of employees, streamlining the process, keeping improvement, paying attention to labor security and product security, preventing defects and errors, as well as carrying out product review and process review. Manuals related to advanced product quality planning (APQP), control plan (CP), potential failure mode and effect analysis (FMEA) are widely adopted in quality management. The ongoing six- intensive lean operation and management pushes the quality management to a higher level. Practices prove that the through-going quality management is relatively well suitable to a modernized steel complex like Shougang Jingtang Steel, while showing central, through-going, highly efficient and optimal features and realizing full-process, from the center to the two ends by extension, integral optimization of quality management.
