What Do The Numbers On A Welding Rod Mean

The last 2 digits together are for the coating and welding current.

E308 l 17 this character may or may not be present and indicates the percentage of carbon in the filler material. This can be found in asme bpvc section ix table qw 442. The numerical value here represents the filler metal that the consumable is made of and will be some grade of stainless steel. The third welding number shows the directions in which you can use the electrodes.

E 6011 or perhaps e 7020. The third number of 1 however indicates that you can use these welding electrodes in all four positions of vertical horizontal flat and overhead. The first letter number combination indicates the chemistry of the weld and will look like a1 b1 b2 b3. The e7018 welding rod is one of the several electrode types with aws designation.

A number grouping has been done on the basis of the chemical composition of the deposited weld metal. Please watch the video given below for more clarity on this topic. After that will come an h number which indicates how much hydrogen will be diffused when you use the rod. The aws assigns four or five digits after the letter.

If the classification starts with 60 for example it means that the welding rod can withstand 60 000 pounds per square inch. Special purpose welding rods may have extra letter and number combinations. The following two numbers indicate the tensile strength of the material in the rod when the weld is stress relieved. For example the lincoln 7018 welding rod numbers show that the tensile strength is 70 000 psi.

For a 6010 rod the coating and current are dictated by the 10. 60 stands for 60 000 psi 70 for 70 000 psi etc. The last number 3 refers to the type of slag flux composition and power supply used for this electrode. The tensile strength of a welding rod can be determined by the first two numbers in the electrode s name.

The first two numbers refer to the tensile strength or how much stress the weld bead can withstand. The next number is the position of the weld. Another type of grouping for filler metal or welding rod is the a number. Most rods that one runs across at the farm supply store will be labeled something like this.

This is measured in thousands of pounds per square inch. As a result the higher the number the stronger the electrode. It is the maximum amount of force a material can take without breaking. The first two welding rod numbers stand for the tensile strength of the filler material.

The e means that it is an electrode suitable for arc welding. For example if it s a horizontal or vertical weld etc a number 1 as in 6010 means it is an all position welding rod and is okay for any position.
