摘　　要：本文介绍了一种新型方法———“T”型支撑杆式测试多孔金属过滤管法兰焊缝强度 ,并从理论上推算出满足焊接强度要求的最小熔深值 ,结合强度测试结果和理论上溶深的最小值 ,判断焊缝质量 。A kind of new-type method--type'T'pole test method was introduced by which the weld strength between porous metals and pipe flange can be determined.The minimum value of weld penetration can be deduced by this method;The quality of the welding seam can be determined by combining the test result with the minimum weldpool depth.The new method can present information on welding practice and post-weld heat treatment.
