Short answer: Weld edge preparation shapes the joint — square for thin stock, single or double V for medium plate, U/J for thick sections — so the weld penetrates fully without excessive filler; the right bevel, root gap and cleaning keep the joint sound and low on distortion.

Why Edge Prep Matters
Without the correct bevel the root never fuses and you waste filler fighting incomplete penetration — a top cause of defects in Weld Defects Guide. Prep follows the joint design used by How To Weld Stainless Steel, How To Weld Carbon Steel e Como soldar alumínio, and the carbon basis in Steel Carbon Equivalent Guide.
Choosing the Bevel
Below ~3 mm a square edge welds in one pass; 3-12 mm uses a single V with a root gap; 12-25 mm a double V to cut distortion; over 25 mm a U or J groove to save filler. Pipe and pressure joints take a compound bevel for full penetration, matching Steel Pipe Fittings Flanges Guide e Pipe Flanges Supplier. Clean the land of oil and oxide per Metal Degreasing Guide.
Tools, Root & Quality
Bevel by plasma, grinding or machining, hold the root face and gap to the WPS, and control heat with Stress Relieving Vs Annealing after. Inspect the prep and root with Metal Ndt Guide; for dissimilar metals follow Dissimilar Metal Welding Guide. We supply plate and pipe with certified edges and chemistry per Mill Test Certificate Guide.

Perguntas frequentes
Below about 3 mm a square edge with no bevel welds in a single pass; just hold a small root gap for fusion.
For plate roughly 12-25 mm thick a double V splits the weld volume between sides, reducing distortion and residual stress.
Above ~25 mm a U/J groove gives full penetration with far less filler and heat than a wide V, saving time and distortion.
The root gap is the space at the joint root that lets the first pass fuse through; too tight starves penetration, too wide sags the root.
