Know your Welding-cost. It appears that the Truth may be disturbing if one lacks the courage to face it and to do something about. As a simple exercise, next time you stroll in the welding shop, just ask the person in charge what is the filler metal weight used per unit weld length, or per hour, of the three most important welding jobs currently being performed. The following is an excerpt from Sell Your Book: A Beginner’s Guide To Book Marketing. a well-made book could cost (in today’s dollars) around $$1, make people want to buy your. Flux cost per meter of weld - $/m Gas cost per meter of weld - $/m Labor cost per meter of weld $/m Shift Productivity kg welded in 8 hr OUTPUT FOR Process 2 Amount of filler metal needed 1 kg Number of passes per joint ~ 6 Amount of shielding gas m^3 Number of Gas Bottles Required 1 Actual welding time hr Deposition Rate File Size: 92KB. Wages and the costs of operation are also a factor. To simplify matters, it is easy to think of the overall costs of a welding job as falling into one or two categories. There are fixed costs, which homeowners incur no matter what type of metal is used or which type of process is used to weld it.

Labor & O/H Rate ($) Enter the Labor & Overhead Rate. The national average is $ Operating Factor (%) Operating Factor is the amount of actual weld time per hour expressed as a percentage. For hand held operations: 50% for MIG and Metal Core 45% for Flux Cored Wires. manual weld times are general estimates, not the best or worst orbital weld times are very accurate, based on the weld particulars given; however they are not the best case. How to Use the Chart: 1) Adjusting Manual Weld Times: The user should compare the weld times and the weld data used against their own application. The appearance of the weld is a good guide to its quality: the smoothness of the profile and the nature of the wash are features deserving particular attention. The ratio of weld strength to that of the parent material was using a single V butt weld and using a double V butt weld. The previous two Connect articles dealt with the mechanics of costing a weld: how to calculate the weld volume and how to calculate the amount of welding consumables required to fill a weld preparation.. The final step in costing a weld is to determine the length of time to deposit this weight of weld metal. This is obviously a function of the deposition rate of the process.

Footof Weld LaborCost Electrode Cost The cost of the electrode per foot of weld is determined by several factors. The first is the weight of electrodes deposited per foot of weld. This is dependent on the size of the weld to be made. The second is the cost per pound of the electrode. The third is the deposition efficiency of the electrode. 8. Cost of the process, including capital expendi-tures, materials, and labor; 9. Number of components being fabricated; Applicable code requirements; and Safety concerns. The overview of the joining processes featured in Table presents an initial reference guide to the capa-bilities of various joining processes with respect to a.   If a 1/4 inch fillet weld costs the fabricator $ per foot, a 1/2 inch fillet weld will cost $ per foot. The cross sectional area of the 1/2 inch fillet weld is four times greater than the 1/4 inch fillet weld, thus it takes four times the volume of weld metal to make and four times longer if everything, i.e., welding pocess, electrode. Cost control emphasis is on past and present. Cost control is applied to things which have standards. It seeks to attain lowest possible cost under existing conditions. Cost control is a preventive function. Aspects of Cost Control: Cost control involves the following .
