Built-up welding example 1
Roll size: Φ 350mm * 3200mm, roll surface is implemented the stainless steel built-up welding, hardness requires 52～56HRC.Select the GY256 welding wire for use, welding parameter is as follows:
| Electric current (A) | Arc voltage (V) | Weldering speed (mm/min) | Interlayer temperature (℃) |
| 300～350 | 28～34 | 350～450 | ≥300 |
Select for use double-handpiece column overlaying welding machine tool and original overlaying welding machine tool to carry out built-up welding respectively, welding parameter is identical, also adopts two dollies to operate on the initial pile welding machine bed.
Comparing result is as follows:
1. the operating efficiency of double-handpiece column overlaying welding machine tool is apparently higher than initial pile welding machine bed: 10.5 hours double-handpiece column overlaying welding machine tool times spent, 12.25 hours initial pile welding machine bed times spent.Initial pile welding machine bed will be used to handle that dolly skids, jam the plenty of time.
2. the quality of double-handpiece column overlaying welding machine tool built-up welding roller is apparently higher than former lathe.Roller A is the product of column overlaying welding machine tool, and roller B is former machine tool product.Extract three sections detection zones from roller centre and two ends respectively, axial length 200mm detects detection zone inside weld quality, the results are shown in following table:
| Roller | Weld width average c (mm) | C ± 0.5mm weld seam proportion (%) | Weld seam difference of height maximum (mm) |
| A | 18.2 | 77 | 0.3 |
| B | 18.6 | 43 | 0.7 |
The roller A that can obviously find out the built-up welding of column overlaying welding machine tool obviously is better than the roller B of former lathe built-up welding from the level and smooth and uniformity coefficient of welding bead.
Example 2, roller, size: Φ 500mm * 2870mm, roll surface is implemented the stainless steel built-up welding, hardness requires 42～48HRC.Select the 0Cr13Ni4MoN welding wire for use, welding parameter is as follows:
| Electric current (A) | Arc voltage (V) | Weldering speed (mm/min) | Interlayer temperature (℃) |
| 260～290 | 28～34 | 300～400 | ≥150 |
Carry out built-up welding at double-handpiece column overlaying welding machine tool and original overlaying welding machine tool respectively, welding parameter is identical, also adopts two dollies to operate on the former lathe.
Comparing result is as follows:
1,22.5 hours double-handpiece column overlaying welding machine tool times spent, 28 hours initial pile welding machine bed times spent.Along with the prolongation of built-up welding time, skidding appears in initial pile welding machine bed built-up welding dolly, the probability of jam phenomenon increases.
2, the quality of double-handpiece column overlaying welding machine tool built-up welding roller is apparently higher than former lathe.Roller A is the product of column overlaying welding machine tool, and roller B is former machine tool product, extracts three sections detection zones from roller centre and two ends equally respectively, and axial length 200mm detects detection zone inside weld quality, the results are shown in following table:
| Roller | Weld width average c (mm) | C ± 0.5mm weld seam proportion (%) | Weld seam difference of height maximum (mm) |
| A | 19.6 | 68 | 0.2 |
| B | 20.2 | 39 | 0.5 |
