Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 As shown, the underwater wet welding quality evaluation system includes a computer and a data collector, and the computer and the data collector are connected through a data line.

[0033] The data collector includes a data acquisition card, a current sensor, a voltage sensor and a voice alarm device built in a high waterproof grade chassis. The current sensor and the voltage sensor are respectively connected to the data acquisition card. The current sensor is used to convert the welding current information into a signal that is easily recognized by the data acquisition card, and to realize the electrical isolation between the data collector and the signal source; the voltage sensor is used to convert the welding voltage information Convert it into a signal that is easy to identify by the data acquisition card, and real...

Abstract

The invention discloses an underwater wet welding quality detecting control method. The underwater wet welding quality detecting control method comprises the steps of inputting of welding specifications, determining of evaluating indexes, automatic judging of arc-striking effect, real-time collecting of information, voice alarming, automatic judging of ending of the welding process and evaluatingafter welding. The underwater wet welding process is interfered timely and effectively with the help of an underwater wet welding quality evaluating system, and the welding quality is accurately evaluated. The underwater wet welding quality evaluating system comprises a computer and a data collecting device; and the computer and the data collecting device are connected through a data cable, and the computer is used for inputting the welding specifications, receiving, preserving and displaying the electrical signal information collected by the data collecting device in the welding process, andprocessing the electrical signal information. Carrying is convenient, and operation is easy.

Description

technical field [0001] The invention belongs to the field of welding technology, in particular to an underwater wet welding quality evaluation system and a welding quality detection and control method. Background technique [0002] The underwater welding and cutting technology has the advantages of high connection strength level and fast cutting speed, and has great application value in the emergency repair of ships. Most of the underwater welding emergency repairs of ships are in-situ welding, and it is difficult to carry out quality inspection after the construction is completed. Welding quality inspection is generally carried out through post-weld non-destructive testing. For underwater wet welding, due to the special circumstances of underwater operation, it is difficult to carry out non-destructive flaw detection. [0003] In the onshore welding process, the online evaluation of welding quality has a relatively mature application: the document "Online Welding Quality ...
