Fillet Welded Seams are the most common type of welding joint. They account for nearly 75% of joints made with arc welding. You do not need to prepare the edge as this type of joint makes it easy to weld piping systems. Butt welds are more expensive than fillet welds. Fillet welds are mostly used in piping systems to join pipe to socket joints.<\/p>\n\n\n\n<p>Cliffswelding claims, welding joints can be prepared&nbsp;in numerous ways including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Casting<\/li>\n\n\n\n<li>Shearing<\/li>\n\n\n\n<li>Machining<\/li>\n\n\n\n<li>Forging<\/li>\n\n\n\n<li>Filing<\/li>\n\n\n\n<li>Stamping<\/li>\n\n\n\n<li>Oxyacetylene cutting (thermal cutting process)<\/li>\n\n\n\n<li>Routing<\/li>\n\n\n\n<li>Grinding<\/li>\n\n\n\n<li>Plasma arc cutting (thermal cutting process)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Corner Outside Seams<\/h3>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/www.hotairtools.com\/blog\/wp-content\/uploads\/2018\/07\/corner-outside-seam.jpg\" alt=\"\" class=\"wp-image-472\"\/><\/figure>\n\n\n\n<p>Corner Outside Seams are one of the most popular welds in the sheet metal industry the corner welding joint&nbsp;is used on the outer edge of the piece.&nbsp; This welding seam is a type of joint that comes together at right angles between two metal parts to form an L.&nbsp; These are common during the construction of boxes, box frames, and similar fabrications.<\/p>\n\n\n\n<p>Welding Styles Used To Create Corner&nbsp;Joints:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Spot weld<\/li>\n\n\n\n<li>Fillet weld<\/li>\n\n\n\n<li>V-groove weld<\/li>\n\n\n\n<li>Square-groove weld or butt weld<\/li>\n\n\n\n<li>U-groove weld<\/li>\n\n\n\n<li>Bevel-groove weld<\/li>\n\n\n\n<li>Flare-V-groove weld<\/li>\n\n\n\n<li>J-groove weld<\/li>\n\n\n\n<li>Corner-flange weld.<\/li>\n\n\n\n<li>Edge weld<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">X-Seams<\/h3>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"253\" height=\"156\" src=\"https:\/\/www.hotairtools.com\/blog\/wp-content\/uploads\/2018\/07\/X-seam-welding.jpg\" alt=\"\" class=\"wp-image-476\"\/><\/figure>\n\n\n\n<p>The double-V seam is also known as an X-seam and double V-joint. It is a type of butt welding seam and consists of a combination of two V-seams on each of the two sides of the components to be joined.<\/p>\n\n\n\n<p>Single butt welds are similar to a bevel joint, but instead of only one side having the beveled edge, both sides of the weld joint are beveled. A double-V joint seam is used in thick metals and when welding can be performed from both sides of the workpiece. <\/p>\n\n\n\n<p>When welding thicker metals, a double-V joint requires less filler material because there are two narrower V-joints compared to a wider single-V joint. The double-V joint helps compensate for warping forces. With a single-V joint, stress tends to warp the piece in one direction when the V-joint is filled, but with a double-V-joint, there are welds on both sides of the material, having opposing stresses, straightening the material.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">V-Seams<\/h3>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"273\" height=\"152\" src=\"https:\/\/www.hotairtools.com\/blog\/wp-content\/uploads\/2018\/07\/V-Seam-welding.jpg\" alt=\"\" class=\"wp-image-475\"\/><\/figure>\n\n\n\n<p>In order to achieve the V-shaped angle that is typical for the V-seam, the workpieces are either beveled or positioned at an appropriate angle to each other. This is required in order to complete a V-Seam welding seam.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Overlap Seams<\/h3>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/www.hotairtools.com\/blog\/wp-content\/uploads\/2018\/07\/Overlap-Seam.jpg\" alt=\"\" class=\"wp-image-473\"\/><\/figure>\n\n\n\n<p>An overlap seam is when one seam overlaps another to\u00a0form a continuously welded and leak tight welding seam.
