Weld Design, Cost and Reference

These tools help plan a weld joint. Calculate fillet weld strength, stitch weld spacing and total welding cost, work out steel’s carbon equivalent, and look up melting points, weld position codes and welding symbols.

Tools in this group

• Carbon Equivalent Calculator — Enter the steel's chemical composition from the mill certificate to get its carbon equivalent by the IIW, Pcm and CET formulas.
• Metal Melting Point Chart — Look up the melting point of a pure metal in °C, °F and K, or enter a temperature to see which metals are solid or molten at it.
• Stitch Weld Calculator — Enter the joint length, weld length and pitch to get how many stitch welds fit, the exact pitch and where each weld starts and ends.
• Weld Strength Calculator — Enter the fillet weld leg, length and electrode to get the load the weld carries, or the weld size or length a load needs.
• Welding Cost Calculator — Enter the weld size and length with your deposition rate and prices to get the filler, time and total cost of a weld.
• Welding Positions Chart — Choose the weld type, plate or pipe, and the orientation to get the AWS position code, the ISO 6947 code and a drawing.
• Welding Symbol Chart and Builder — Choose the weld type, side, size and extras to draw a welding symbol and read what it means; every basic weld symbol is charted below.
