Half Round Aluminum Extrusion Many people start welding aluminum extrusion and find that cracks, porosity, and warped shapes appear. This always happens when filler, cleaning, and TIG settings are not correct. To TIG weld aluminum extrusion properly, you need the right filler rods (like ER4043 or ER5356), thorough cleaning, correct TIG parameters, and sometimes backing […]<\/p>\n","protected":false},"author":6,"featured_media":7033,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_analysis_target_kw":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-26477","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-custom-mold"],"meta_box":{"post-to-quiz_to":[]},"_links":{"self":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/posts\/26477","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/comments?post=26477"}],"version-history":[{"count":0,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/posts\/26477\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/media\/7033"}],"wp:attachment":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/media?parent=26477"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/categories?post=26477"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/tags?post=26477"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
