For example Manufacturer A may call a tip that cuts 12-inch steel a Number 1 while Manufacturer B calls it a Number.

How to read welding wire numbers. Stocks in huge qty. ER An electrode or filler rod that is used in either a MIG wire feed or TIG welding. The first two numbers of a 4 digit number and the first 3 digits of a 5 digit number indicate the minimum tensile strength in thousands of pounds per square inch of the weld that the rod will produce stress relieved.

The E stands for arc welding electrode. The E indicates an arc welding electrode. Multi-pass welding or a beveled joint design may be required for material thickness 316 and greater depending on power output capability.

The prefix E designates an arc welding electrode. The first letter-number com-bination gives the type and size of the longitudinal wire the second. MIG Wire Electrode Label Meaning for a ER70S-6 Label.

6 The amount of deoxidizing agent and cleansing agent on the electrodeThis is a copper coating on the electrode and there are different types too. The first part simply tells you which standard is used. An example is 6 by 8W80 by W40.

Electrodes are usually coated with varying chemicals to protect the joints when welding. Ad Nickel Alloy Electrodes supplier stockist. We Offer Specialized Welding Solutions in Inconel Monel Incoloy.

The next to last digit indicates position. For example E6010 is a 60000 psi tensile strength electrode while E10018 designates a 100000 psi tensile strength electrode. Check with your machine manufacturer for any information that may pertain to your welding system.

After that will come an H number which indicates how much hydrogen will be diffused when you use the rod. We Offer Specialized Welding Solutions in Inconel Monel Incoloy. The strength of shading on a welding lens is given as a numerical value with 4 being the lowest and 13 the highest more on that below Which welding lens is darkest.

The next to last digit indicates position. The length of the fillet weld if it is not the entire length of the join is displayed to right side of the symbol. A number 2 would indicate a flat and horizontal electrode only we skip the number 3 and a number 4 would identify your electrode as being able to weld only flat horizontal vertical down and overhead.

The first letter-number combination indicates the chemistry of the weld and will look like A1 B1 B2 B3. ER70S-6 wire can provide better wetting at the weld toe when compared to an ER70S-3 wire. Ad Nickel Alloy Electrodes supplier stockist.

Stocks in huge qty. The first two digits of a 4-digit number and the first three digits of 5-digit number indicate minimum tensile strength. Intermittent welds are called out using Length and Pitch.

Welded wire fabric is designated by two numbers and two letter-number combinations. Better wash-in may be a requirement in applications subject to fatigue. We ship worldwideCall us.

For example E6010 means 60000 pounds per square inch PSI tensile strength and E10018 means 100000 psi tensile strength. This value may or may not appear printed on the consumable. The number 1 indicates an All-position electrode.

The first two digits of a 4-digit number and the first three digits of a 5-digit number stand for tensile strength. Next will be either a 4 or 5 digit number stamped on the electrode. In this example its the American Welding Society numbering system.

This number is an indicator of applicable weld position. 70 A minimum of 70000 pounds of tensile strength per square inch of weld. ER70S-6 is also better for creating a smooth transition from the weld to the base metal also known as wash-in or tie-in.

The kind of shaded welding lens you need will largely come down to the type of welding youll be doing the material youre welding and the amps youre using. AWS E6011 The E in this example represents the consumable type. We ship worldwideCall us.

DOUBLE-CLICK on Chart to View Quick guide for selecting MIG wire size and welder amperage for your application. Sizing and standardizing cutting welding and heating tips can be a real challenge because manufacturers assign numbers to their tips that have no relationship to bore size material thickness or anything else see Figure 5. Extra Numbers and Letters Special-purpose welding rods may have extra letter and number combinations.

As noted above the number to the right of the diagonal line of the fillet symbol is the length in the US this will be in inches unless otherwise noted. A number 1 on the third digit therefore basically means that it can be used for all four welding positions. The first number gives the spacing in inches of the longitudinal wire s the second g i v es the spacing of the tra n s ve r s e w i re s.
