the quality of the weld bead generated by the welding system [10]. Distance sensors are also used to identify and track the weld seam during inspection [11]. Seam tracking systems have been developed to guide a weld gun along a weld seam to improve weld bead quality. For these systems, online inspection of the weld bead is still needed to

Busbar Weld If we consider the weld to the busbar to be a resistor, measuring the impedance is as simple as connecting a current source to the weld and measuring the voltage as shown in Figure 2. HI Current Source LO HI Voltmeter LO Weld Figure 2: Simple weld resistance circuit. The impedance of the weld is then calculated using Ohm's Law.

One camp says to weld, test the weld and then expand; another says expand, weld and then test the weld. The purchaser must ultimately make the decision for which sequence to use. Figure 9 lists the steps to follow if "weld tube ends-and then . seal weld during the expansion step is eliminated. In addition

The most basic element of a welding symbol is the “weld symbol” itself, which tells what type of weld is required: fillet weld, groove weld, plug weld, etc. For groove welds, the type of joint preparation is specified by the weld symbol. There are 17 different we

Size of fillet weld (S) : The sides containing the right angle of the fillet weld are called legs. The size of the weld is specified by the minimum leg length.

thickness and weld cross-section. ISOEDGE analysis was queried to find a 304SS edge weld with the same weld area. The analysis indicates that only 83 watts is required to make the weld. Which yields an energy transfer efficiency (absorption) of 17% (83/475) for the defocussed weld.

joints. The weld joints do influence the strength of the weld in these conditions. In ASME Boiler and Pressure Vessel code the reduction in strength is tuned in by incorporating weld strength reduction factors in calculations. As far as the weld deposition process is concerned, in cases where the weld between stub and pipe in which all

stresses for weld metal in fillet welded joints under static loading. The calculation of design load is based on the assumption that the throat of welds is the critical section. The criterion for weld size deter mination is to let the combined stress in the effective weld area (effective weld throat times joint length) be less than the

For welds not ground smooth the transducer is placed alongside and not quite parallel to the weld and moved along the length, Fig. A-10. The entire weld and heat affected zone should be scanned. The weld should be inspected from both sides of one surface.

Figure 8 - Spot weld in the reality and in the simulation The discretization of the spot weld (Figure 9) can be modeled by a simple solid element (hexahedron) or by any number of solid elements, building a spot weld assembly (cluster). The cluster modeling has some advantages compared to the single element weld because

Weld Line Optimization Identifying necessary weld line locations and reducing weld lines through topology optimization is also possible using Inspire. In this example, the stress and displacement levels were set to stay within a given limit resulting in a weld reduction of around 85%, from 728mm to 111mm of overall weld line space.

The weld joint contains weld length and volume, bevel and fillet data, and inspection requirements, and can be used to manage the entire lifecycle of the weld. The weld joint data is used by structure manufacturing to automatically apply edge preparation and to generate drawing and product and manufacturing information (PMI) weld symbols.

stud is then forced (or "plunged") by the weld gun into the molten pool and held in place until the metals resolidify. This high quality fusion weld is completed in milliseconds. 1. Stud is placed against workpiece and weld gun trigger depressed 2. Stud is lifted by weld gun and "initiating arc" is drawn 3. Weld gun forces stud into molten metal 4.

was approximately the same size as the Inconel 718 weld, it is assumed that the HAZ dimension would also be similar. Therefore, crack starter notches for CRES 321 specimens are offset from the notch center by the same dimensions as the Inconel 718 specimens: (1) weld center, (2) 1.82 mm from the weld center, or (3) 2.84 mm from the weld center.

Reliable detection of weld size, cold weld, and surface indents with sufficient accuracy for various combination of materials, thickness, stack-up configuration, surface coating conditions and welding conditions.

time intervals from completion of welding to weld inspection of the final weld pass were reviewed for MSBs loaded to date. It was determined from this data that the expected maximum delay times associated with each weld are less than the time interval from completion of welding to inspection of the weld.

Converting Decimals into Fractions Decimals are an almost universal method of displaying data, particularly given that it is easier to enter decimals, rather than fractions, into computers. But fractions can be more accurate. For example, 1 3 is not 0.33 it is 0.33̇ The method used to convert decimals into

Weld studs can be installed in the down-hand, horizontal and over-head positions. The drawn arc stud welding process produces welds that provide a solid bond between a metal stud anchor and base metal. Ceramic ferrules are needed to properly weld drawn arc weld studs.

Weld ring gaskets in Profile A22 are, like A23 and A24, 2x15 30 mm thick therefore providing enough room to weld without special flanges, as shown in the illustration. This results in large bolt lengths with good spring suspension. As all weld seams are external, any irregularities can easily be re-welded.
