This page lists down detailed and information rich UFT (formerly QTP) Tutorials for beginners as well as experienced users of UFT. If you are a beginner, it is advised that you go through the articles one after the other as mentioned in the list. So let's get started UFT/QTP Tutorials for Beginners. What is QTP Tutorial? HP QuickTest Professional (QTP) is an automated functional testing tool that designed to apply automated regression testing to find out the gaps, errors/defects in contrary to the actual/desired results of the application under test. Qtp tutorial for beginners. This tutorial is designed for Software Testing Professionals with a need to understand the QTP in detail along with its simple overview, and practical examples. This tutorial will give you enough ingredients to start with QTP from where you can take yourself at higher level of expertise.

Visual Weld Inspection Acceptance Criteria

Weld visual inspection shall be performed by personnel trained through an established program that reflects the intent of the recommended guidelines provided in ASNT-TC-1A, EN473, AWS B1.11, CAN/CGSB-48.972-2000, or EN 970. Ideneb 1.3. Personnel conducting weld visual inspection for final product acceptance shall. The Visual Weld Inspection Checklist is recommended as a best practice for supplier's approved weld inspectors. 4.5 The inspectors' tool kit shall include, as a minimum, the following tools: VISUAL WELD INSPECTORS TOOL KIT TOOL TOOL REQUIREMENT RECOMMENDED Flashlight Xenon or Krypton bulb 2AA or 2AAA size batteries Fillet Weld Gages Standard. Visual Inspection Responsibilities. When – Final visual inspections must be performed: a) When the weld is complete, and in the final sur-face and heat treated conditions b) Before other NDT (when required) c) Before being made inaccessible for inspection 2. Where – the weld inspection zone: a) All work - Completed weld faces plus ½ inch on.

ASME B31.3 Acceptance criteria for welds

Peers,
As per ASME B31.3 Table 341.3.2 Acceptance criteria for welds, is it important to meet all the acceptable values mentioned in the criteria. For eg. lack of root penetration for Normal and Category M fluid - Girth, Miter groove and branch connection shows B as acceptance criteria. Notation B has two acceptable values in the table. One for depth i.e. <1mm and <0.2Tw (both are less than or equal to) and the other for cumulative length i.e. <38mm (also less than or equal to) in any 150mm weld length. Does this mean that both depth and length should be within the limits to accept the weld. RT cannot detect the depth as it is 2D image, so if in this case when the depth cannot be determined, is it possible to reject the weld? Is there an interpretation of this available from ASME?
Appreciate your help.
AWSD1.1 Visual Inspection Acceptance Criteria
All welds shall be visually inspected and shall be acceptable if the criteria of Table 6.1 AWS D1.1 are satisfied.
To more explanation about Visual Inspection Acceptance Criteria you can open AWS D1.1 section 6 (inspection) part C.

Before you inspect and make decision about weld as per AWS D1.1, you must know definitions of:
Visual
1. Statically Loaded Nontubular Connections (more detail see Section 2 part B AWS D1.1)
2. Cyclically Loaded Nontubular Connections (more detail see Section 2 part B,C AWS D1.1)
3. Tubular Connection (all Load) (more detail see Section 2 part D AWS D1.1)
Criteria
Below Summary Visual Inspection Acceptance Criteria As per AWSD1.1 Table 6.1 :
- Any Crack shall be unacceptable, regardless of size or location

Visual Weld Inspection Criteria

- All craters crack (start/end) shall be filled, except for the end of intermittent fillet weld outside of their effective length
- All weld profiles shall be free from cracks, overlaps, and the unacceptable profile discontinuities exhibited in Figure 5.4.

- All weld profiles shall be free from cracks, overlaps, and the unacceptable profile discontinuities exhibited in Figure 5.4.
- Visual inspection of welds in all steels may begin immediately after the completed welds have cooled to ambient temperature. Acceptance criteria for ASTM A 514, A 517, and A 709 Grade 100 and 100 W steels shall be based on visual inspection performed not less than 48 hours after completion of the weld.
- The size of a fillet weld in any continuous weld may be less than the specified nominalsize (L) without correction by the following amounts (U) on Table 6.1
- Undercut and porosity see more detail on Table 6.1
Methods of Testing and Acceptance Criteria for WPS Qualification (Section 4) Visual Inspection.
For acceptable qualification, welds shall meet the following requirements:

Visual Weld Inspection Acceptance Criteria Example

(2) All craters shall be filled to the full cross section of the weld.
(3) The face of the weld shall be flush with the surface of the base metal, and the weld shall merge smoothly with the base metal. Undercut shall not exceed 1/32 in. [1 mm]. Weld reinforcement shall not exceed 1/8 in. [3 mm].

Aws Visual Inspection Criteria

(4) The root of the weld shall be inspected, and there shall be no evidence of cracks, incomplete fusion, or inadequate joint penetration. A concave root surface is allowed within the limits shown below, provided the total weld thickness is equal to or greater than that of the base metal.

Visual Weld Inspection Acceptance Criteria Template

(a) The maximum root surface concavity shall be 1/16 in. [2 mm] and the maximum melt-through shall be 1/8 in. [3 mm].
(b) For tubular T-, Y-, and K-connections, melt-through at the root is considered desirable and shall not be cause for rejection.
