Claims
- 1. An inspection method of single butt weld zone comprising the steps of:forming a concave portion having a width and a depth on a butt surface of at least one side of weldments where a single butt welding is carried out by a fusion welding method using a filler metal, wherein the width(2W) of the concave portion concaved to both sides interposioning a butt portion formed on groove surfaces therebetween is within a range of about 1 through 60% of a predetermined width of a formed penetration bead and the depth(D) along a thickness of the concave portion is within a range of 1 through 50% of a thickness of the weldments; carrying out the single butt welding such that the concave portion does not remain after the single butt welding; and inspecting the single butt weld zone by an ultrasonic test.
- 2. An inspection method of single butt weld zone comprising the steps of:forming a concave portion having a width and a depth on a butt surface of at least one side of weldments where a single butt welding is carried out by a fusion welding method using a non filler metal, wherein the width(2W) of the concave portion concaved to both sides interposining a butt portion formed on groove surfaces therebetween is within a range of about 1 through 40% of a predetermined width of a formed penetration bead and the depth(D) of a thickness direction is 7% and less of a metal volume of a weld zone; carrying out the single butt welding such that the concave portion does not remain after the single butt welding; and inspecting the single butt weld zone by ultrasonic test.
- 3. An inspection method of single butt weld zone comprising the steps of:forming a concave portion having a width and a depth on a butt surface of at least one side of weldments where a single butt welding is carried out by a fusion welding method using a filler metal, wherein the width(2W) of the concave portion concaved to both sides interposioning a butt portion formed on groove surfaces therebetween is within a range of about 1 through 60% of a predetermined width of a formed penetration bead and the depth(D) along a thickness of the concave portion is within a range of 1 through 50% of a thickness of the weldments; carrying out the single butt welding such that the concave portion does not remain after the single butt welding; and inspecting the single butt weld zone by a radiograph test.
- 4. An inspection method of single butt weld zone comprising the steps of:forming a concave portion having a width and a depth on a butt surface of at least one side of weldments where a single butt welding is carried out by a fusion welding method using a non filler metal, wherein the width(2W) of the concave portion concaved to both sides interpositioning a butt portion formed on groove surfaces therebetween is within a range of about 1 through 40% of a predetermined width of a formed penetration bead and the depth(D) of a thickness direction is 7% and less of a metal volume of a weld zone; carrying out the single butt welding such that the concave portion does not remain after the single butt welding; and inspecting the single butt weld zone by a radiograph test.
