北美焊接协会第五届年会于1989年10月在哥伦比亚召开。会议期间学术界和工业界的代表们就塑料和复合材料连接工艺发表了最新研究的成果报告,以供研究和工业部门使用。为了使产品有更大的竞争力,就要求使用塑料和复合材料,才能满足产品质量轻、强度高和成本低的要求。随着使用塑料和复合材料比例的增加,就要求使用机械紧固件连接、粘接剂和焊接连接。焊接能提供快、干净和经济的连接,并能沿接头均匀分布载荷。机械紧固件连接会使质量和成本增加,应力集中。而粘接剂连接要求进行表面制备、一定的固化时间,并会逸出难闻的气味。
The Fifth Annual Meeting of North American Welding Society was held in Colombia in October 1989. During the conference, academics and industry representatives delivered reports on the latest research on plastic and composite joining processes for use by research and industry sectors. In order to make the product more competitive, it requires the use of plastic and composite materials to meet the requirements of light weight, high strength and low cost. With the increasing use of plastic and composite materials, the use of mechanical fasteners, adhesives, and welded connections is required. Welding provides fast, clean and economical connections and distributes loads evenly along the joint. Mechanical fasteners will increase the quality and cost, stress concentration. The adhesive connection requires surface preparation, a certain curing time, and will escape the bad smell.
